The following C program i have taken from book but output is not coming- Solution required- kindly help.

Question

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);
    }

Answer 1

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);
    }

Answer 2

int p in mul function definition is not inside the function make it declare in the function and give return 0 in main function

Answer 3

In the above program, during the declaration of function you have written

int mul(int a,int b);

and when you have defined te function then you have written

int mul(int x,int y)

which is absolutely wrong. So your function should be defined like this :-

int mul(int a, int b)

Answer 4

#include <stdio.h>

int 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);
}

Answer 5

You opened a brace after the first statement "int p;", where it should be after the function begins(before the statement). The entire function should be wrapped inside the braces.

int mul (int x, int y)
{

    int p;
    p = x*y;
    return(p);
}

 

Answer 6

Curly brace for function needs to be before int p; like ...int y){

Recommend defining function before main since easier to understand. This works:

#include <stdio.h>

int mul(int a, int b){
    int p = a*b;
    return p;
}

void main()
{
    int a, b, c;
    a = 5;
    b = 10;
    c = mul(a,b);
    printf ("multipilcation of %d and %d is %d",a,b,c);
}

Answer 7

use int p;

inside the function, basically inside the flower brackets or globally after the function declaration

int mul(int, int)

{

int p;

}

Answer 8

#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 = x*y;
        return(p);
    }

Answer 9

multiplication of 5 and 10 is 50

5

10

50

Answer 10

#include <stdio.h>

int mul(int x, int y){
    
    int p;
    
    p = x*y;
        
        return p;
}
    
void main()
{
    int a, b, c;
    a = 5;
    b = 10;
    c = mul(a,b);
    printf ("multipilcation of %d and %d is %d",a,b,c);
}
