The document describes a C program that computes a sum based on nested loops. The function 'fun' takes an integer 'n' and adds odd integers starting from 'j' up to 'n'. The program calls this function with 'n' equal to 6 and prints the result.

1. Predict the output of the following C program:
#include <stdio.h>
int fun(int n){
int i, j, k, sum = 0;
for(i=1;i<=n;i++)
for(j=i;j<=n;j++)
for(k=j;k<=n;k+=2)
sum=sum+k;
return sum; }
int main(){
printf("%d", fun(6));
return 0; }
