Need Help :programming with function

[Techtree]

I tried to use switch statement with function into it.Cant make out where i made error .


Program :

#include<stdio.h>
void main()
{
int a,b,sum,mul;
int i;
printf("enter the value of a,b ");
scanf("%d%d",&a,&b);
printf("1.ADD 2.MULTIPLY");
scanf("%d",&i);
sum=add(a,b);/*function calling*/
printf("the value is %d",sum);
mul=pli(a,b);/*function calling*/
printf("the value is %d",mul);
}
switch(i)/*quite confused with this part of code*/
{
case 1:
add(int x, int y)/*fuction called*/
{
	int z;
	z=x+y;
	return(z);
	break;
}
case 2:
	pli(int k,int l)/*function called*/
	{
		int m;
		m=k*l;
		return(m);
		break;

}
	}

Error:
Syntax error switch:

What is this ? Are trying to do some magic with switch .You can not use switch outside of the main or other functions . But in your code you used switch out of the block.

[Alexander jack]

why switch case outside main function !!!

[Alexander jack]

why not you prefer to call the function inside switch case instead of defining inside it.
Have any specific reason !!!!

Got it .Thanks

For starters, you need to indent your code properly, e.g.,

#include<stdio.h>

void main()
{
    int a, b, sum, mul;
    int i;

    printf("enter the value of a,b ");
    scanf("%d%d", &a, &b);

    printf("1.ADD 2.MULTIPLY");
    scanf("%d", &i);

    sum = add(a, b); /*function calling*/
    printf("the value is %d", sum);

    mul = pli(a, b); /*function calling*/
    printf("the value is %d", mul);
}

switch(i)/*quite confused with this part of code*/
{
case 1:
    add(int x, int y)/*fuction called*/
    {
        int z;
        z = x + y;
        return(z);
        break;
    }
case 2:
    pli(int k,int l)/*function called*/
    {
        int m;
        m = k * l;
        return(m);
        break;
    }
}

So, as has been pointed out, one problem is that you have a switch statement outside of function scope. It looks like you really want to define two functions named add and pli instead of having that switch statement. If so, you should declare those functions before the main function (which should have a return type of int). After that, you can re-introduce the switch into the main function.

Yep. Noted Thanks
