i think (rand()%25)+1 generates random number between 1-25, instead of 0-25, Bucky. No worries, still love you.

errors for line 11 [howMany] . “expression must have a constant value” “expected constant expression” ” cannot allocate an array of constant size()” ” ‘goals’ : unknown size” even I copied this all code correctly and pasted it, those errors pop up.. plz help me someone..

please bucky organise your code for us plz:
int i, temp, swapped;
int howMany = 10;
int goals[15]; //here plz use different no(s) so that we dont get confused.

printf(“Original Listn”); //in the other list you kept the printf b4 the loop plz be uniform
for(i=0; i

What if I want to make a random number from 50 to 99? How can I put like a minimum number for the random numbers that will be printed?

-_- I don’t understand whats going on with the “swapped” variable. NEED HELP!!!

can you make a video on how to compare the numbers in an array from user input? A frequency program that will count how many of the number(s) are the same?

WHY DOESN’T IT WORK WHEN I PUT SWAPPED = 0 BEFORE WHILE LOOP ??

can someone help me and tell me why this code doesnt work. I would really appreciate that

#include
#include
#include
#include
#include

int main()
{
int counter, temp, swapped;
int howMany = 10;
int goals[howMany];

printf(“Original list: n”);
for(counter = 0; counter < howMany; counter++) { goals[counter] = (rand()%25) + 1; printf("%d n", goals[counter]); } while(1) { swapped = 0; for(counter = 0; counter < howMany-1; counter++) { if(goals[counter] > goals[counter+1])
{
int temp = goals[counter];
goals[counter] = goals[counter+1];
goals[counter+1] = temp;
swapped = 1;
}

}
if (swapped == 0)
break;
}
printf(“nsorted list: n”);
for(counter = 0; counter < howMany; counter++); { printf("%d n", goals[counter]); } return 0; }

While starts endless loop
The variable swapped flags condition as sorted, defined as 0, (1 means unsorted)
The for loop embedded exchanges current with next value position if current>next
for 10 times.
Once out of the for loop, if the array isn’t sorted, swapped will have the last value of 1
meaning not sorted.
The following if statement will not break and will go back up to while and redefine
swapped as sorted, i.e. equal to 0 again.
Then tje for loop embedded will go through the sort again. If this time all values are sorted
then the value of swapped will remain 0 and the while loop will break once it hit the outer
if statement
Array is now sorted.
Keeping track of the brackets associated with while, for, and if statement is crucial to avoid confusion. Here my program:

int main()
{

int i, temp, swapped; //i counter, temp swapped
int howMany = 10; //how many variables
int goals[howMany]; //array containing numbers to sort

for (i=0; igoals[i+1]) //loop this howMany times
{
int temp = goals[i];
goals[i] = goals[i+1];
goals[i+1] = temp;
swapped = 1;
}

}

if (swapped == 0)
{
break; //once outside the for loop, break
//array is fully sorted by for loop
}

}

printf(“nSorted Listn”);
for(i=0; i

The random number generator code generates numbers between 1 to 25, and not 0 to 24, because of +1 there. am I right?
thanks for the great videos, Bucky 🙂

#include
#include
#include

main()
{
int ctr, inner, outer, didSwap, temp;
int nums[10];
time_t t;

//If you don’t include this statement, your program will always generate the same 10 random numbers
srand(time(&t));

//The first step is to fill the array with random numbers from (1-100)
for (ctr = 0; ctr < 10; ctr++) { nums[ctr] = (rand() % 99) + 1; } //Now list the array as it currently is before sorting puts("nHere is the list before the sort:"); for (ctr = 0; ctr < 10; ctr++) { printf("%dn", nums[ctr]); } //Sort the array for (outer = 0; outer < 9; outer++) { didSwap = 0; //Become 1 (true) if list is not yet ordered for (inner = outer; inner < 10; inner++) { if (nums[inner] < nums[outer]) { temp = nums[inner]; nums[inner] = nums[outer]; nums[outer] = temp; didSwap = 1; } } if (didSwap == 0) { break; } } //Now list the array as it currently is after sorting puts("nHere is the list after the sort:"); for (ctr = 0; ctr < 10; ctr++) { printf("%dn", nums[ctr]); } return (0); }

For those who dont get temp variable, imagine you have a cup of juice and a cup of milk, and you want to switch the liquids in those cups so in the milk cup there is juice and vice versa. You cant just pour milk in the juice cup so you take third cup and do the following:
1)Pour milk in the third(empty) cup
2)Then pour juice from the juice to the milk cup
3)From that third cup(which now has milk) pour milk in the now empty juice cup
Hope this helps

for bubble sort -program if i take input from user of what nummber of elements he want to sort what changes will occur

While(1){
swapped==0;
for(i=0;I<9;i++){
If(goal[i]>goal[i+1]){
temp=goal[i];
goal[i]=goal[i+1];
goal[i+1]=temp;
Swapped==1;
}

}
If(swapped==0){
break;
}

why you use int howMany = 0; instead of just write a number 10 ?

you initialized “temp” twice (once on the 1st line and one in the for loop). Is that correct? How can the code still be compiled?

First time I found a Bucky program difficult. I liked the challenge, keep at it man!

You can also do it this way:
#include
#include

#define MAXSIZE 10

void read_into_array(int A[], int n);
void print_arrays(int A[], int n);
void sort_arrays(int A[], int n);
void int_swaps(int *, int *);

int
main(void){
int A[MAXSIZE];

read_into_array(A, MAXSIZE);

printf(“Original Listn”);
print_arrays(A, MAXSIZE);

sort_arrays(A, MAXSIZE);

printf(“Sorted Listn”);
print_arrays(A, MAXSIZE);

return 0;
}

void
read_into_array(int A[], int n){
int i;
for (i = 0; i < n; i++) { A[i] = (rand() % 25) + 1; } } void print_arrays(int A[], int n){ int i; for (i = 0; i < n; i++) { printf("%dn", A[i]); } printf("n"); } void sort_arrays(int A[], int n){ int didswaps, i; didswaps = 1; while (didswaps) { didswaps = 0; for (i = 0; i < n-1; i++) { if (A[i] > A[i+1]) {
int_swaps(&A[i], &A[i+1]);
didswaps = 1;
}
}
}
}

void
int_swaps(int *x1, int *x2){
int temp;
temp = *x1;
*x1 = *x2;
*x2 = temp;
}

why my rand() function always generating the same sequence of random number everytime I run it? Why it’s not generating the new random number just like bucky did in this video? Can someone please explain it to me?

Too tiny, I can’t follow along with your text… sawweee[sorry]
