Write and compile the C programs in lenux g Comment equation

Write and compile the C++ programs in lenux (g++) Comment.

equation for the 1st one is n(n+1)/2

Write a C program to find the sum and average of first n natural numbers. The user inputs the value of n. Comment your C code. Write a C program to find the largest and smallest of n non-zero positive integers. The user will input the value of n followed by each of the n values. Comment your C code. Write a C program to find factorial of an integer n. The user inputs the value of n. Do not use recursion. Comment your C code.

Solution

1)

#include <stdio.h>

int main()
{
   int n;
   scanf(\"%d\",&n);
   double avg = (n+1)/2.0;
   printf(\"The average of first %d numbers is %lf\ \",n,avg);

   return 0;
}

2)

#include <stdio.h>

int main()
{
   int n,min,max,temp,i;
   scanf(\"%d\",&n);

   if(n>0)
   {
       scanf(\"%d\",&min);
   }

   max = min;

   for(i=1;i<n;i++)
   {
       scanf(\"%d\",temp);
       if(temp>max)
       {
           max=temp;
       }
       if(temp<min)
       {
           min=temp;
       }
   }

   return 0;
}
