Here’s my take on the conversion to USD program

void convert_to_USD (float euro);

int main (void)
float euro_price = 0.00;

printf(“Enter euro amount: n”, euro_price);
scanf(“%f”, &euro_price);

return 0;

void convert_to_USD (float euro)
float usd = euro * 1.37;

printf(” %.2f Euros is equal to %.2f USD n”, euro, usd);

You are my new C programming professor. Thank you for helping me figure out my homework! I am so glad that there is a resource like this that is available. You’re content is very helpful, I appreciate it.

Muhammad Salman says:

I have a variable let say int c in a given function. I want to pass it to the other class let say it is function(int a, int b, int c); I want only to pass the third argument while ignore the first two. i.e. I just want to pass int c, as function (c) and it just pass it to the third argument. I dont want to pass it like function(0,0,c); .. Is there any possibility. Please advise.

cin >> guess;
if (guess < hidden_number) { cout << "guess higher" << endl; } if (guess > hidden_number) {
cout < < "guess lower" << endl; } if (guess == hidden_number) { cout << "congrats it took you " << gss << " guesses" << endl; break; } } int Itemp; cin >> Itemp;

You miss Command line arguments !.

Corazon Lian says:

why the variable can store the value

TheLast Dragon says:

so I googled euros/dollar exchange rate and now they’re different, cause the market never fluctuates…….

brad long says:

I’m surprised your compiler isn’t warning you about assigning doubles into float variables. I thought the literals defaulted to double when you don’t specify “f” after them. For example: float europrice1 = 1.00f;

DivoN RaY says:


/* Bucky can u check into this code pls…what’s wrong with this ???????Whenever i run this . … no matter wat i give as user inputs in this piece scanf(” %.2f”, &dollar1);
eg. $2.00 or whatever after ENTER it only gives > .0.00 USD = 0.00 Rupee < */ #include

void convertToRupee(float dollar);

int main()
float dollar1;

printf(“Converting Dollar to Rupeesn”);
printf(“Enter Dollar Amount :$”);
scanf(” %.2f”, &dollar1);


return 0;

void convertToRupee(float dollar){
float rupee = dollar * 66.84;
printf(“%.2f USD = %.2f Rupeen”,dollar,rupee);
