What is the output of the following c program. Why, Can you tell me how do you solve it?
THE GIVEN SOURCE CODE IS:
#include<stdio.h>
int fun(int n)
{
if(n==0) {
return 1;
}
else
return 7 + fun(n-2);
}
int main(){
printf("%d",fun(4));
return 0;
}
THE OUTPUT OF THE ABOVE PROGRAM WILL BE: 15
THE SCREENSHOT OF THE OUTPUT IS BELOW:
DETAILED EXPLANATION:
IN THE main() WE CALL fun(4).
THEN IT WILL SEARCH FOR fun() OUTSIDE A main().
IF fun() FOUND THEN IT WILL EXECUTE ALL THE INTRUCTIONS INSIDE IT.
cases:
fun(4):
here n!=0 so the return value is 7+fun(4-2) //output=7
fun(2):
here n!=0 so the return value is 7+fun(2-2) //output=7+7
fun(0):
here n=0 so return value is 1 //output=7+7+1=15.
I HOPE THIS WILL HELP YOU.........

1. What is the output of the following program? include <stdio.h> int wilma (int x) if (x<5) x = 7; return (x) int main (void) int x-1 x=wilma (x) ; printf ("%d", x); return (0) b)3 c) 4 d) 7 a) 1 e) none of these
6. Consider the following program: #include <stdio.h> main() { int a,b,c,d ; a=0; while (1) { printf("%d\n", a); printf("Input? "); scanf("%d",&c); if (c == 0) break; d=0; for (b=1; b<=c; b++) if (c%b == 0) d++; if (d == 2 11 C == 1) a=a+c; } } What does this program do? Rewrite the code, organizing it using sound principles. Include comments and redo variable names and indentation. Use multiple functions, blocks, and/or preprocessing if you deem it necessary.
