#inclue<conio.h>
main()
{
        int t,r,range,i,j,s,d;
        int a[5],b[5];
        long n;
        clrscr();
        printf("Enter no. of numbers for combination : ");
        scanf("%d",&d);
        printf("\nENter numbers for combination : ");
        for(i=0;i<d;i++)
           scanf("%d",&a[i]);
           printf("\nEnter the range : ");
           scanf("%d",&range);

Write A Program To Find The Sum Of The Given n Integers Using An Array

/*Program To Find Sum Of n Integers*/
#include<stdio.h>
#include<conio.h>
main()
{
    int x[50],n,i,sum;
    clrscr();
    printf("\n How many integers??");
    scanf("%d",&n);
        /*loop to read N integers*/
