#include <stdio.h>
#include <stdlib.h>

int main()
{
   int a,b,c,d;
   /*DYNAMIC*/
   printf("\n\t enter the value of a= ");
   scanf("%d",&a);
   printf("\n\t enter the value of b= ");
   scanf("%d",&b);
    printf("\n\t enter the value of c= ");
   scanf("%d",&c);
   d=a+b+c;
   printf("\n\t the sum of three number  are = %d",d);
    return 0;
}

The output

enter the value of a= 2

enter the value of b= 2

enter the value of c= 2

the sum of three number  are = 6
