Once check this.

#include <stdio.h>

int mul (int a, int b);

main()

{

int a, b, c;

a = 5;

b = 10;

c = mul (a,b);

printf ("multipilcation of %d and %d is %d",a,b,c);

}

int mul (int x, int y)

{

int p;

p = x*y;

return(p);

}

#include <stdio.h>

int mul (int a, int b);

main()

{

int a, b, c;

a = 5;

b = 10;

c = mul (a,b);

printf ("multipilcation of %d and %d is %d",a,b,c);

}

int mul (int x, int y)

{

int p;

p = x*y;

return(p);

}

Actually the program is correct but declaring local variable in function is old-style.so you may be using updated complier. so that it may show error.

Use the same argument names while defining the function.

Use int mul (int a, int b) instead of int mul (int x, int y)

ThatÂ´s the code properly running. Cheers

there is your error!
