C Programming

Final Question SPL                                                  


ARRAY RELATED PROBLEMS:

1. Write a C program to get user input of  n integers in an array and print the elements in reverse order.

#include<stdio.h>
int main(void)                                                                                        
{
      int i,n;
      printf("\n  Enter the size of the ARRAY: ");
      scanf("%d", &n);

      int a[n];
      printf("\n  Enter elements: ");
      for(i=0;i<n;i++){
            scanf("%d", a+i);
      }
      puts("\n\n  The reversed elements are: ");
      for(i=n-1;i>=0;i--){
            printf("%4d", *(a+i));
      }puts(" ");
}

2. Write a C program to get user input of n integers in an array and sum all the elements.

 #include<stdio.h>
int main(void)
{
      int i,n,sum=0;
      printf("\n  Enter the size of the ARRAY: ");
      scanf("%d", &n);
      int a[n];
      printf("\n  Enter elements: ");
      for(i=0;i<n;i++){
            scanf("%d", a+i);
      }

            sum+=a[i];
      }printf("\n  The sum=%d\n", sum);
}

      printf("\n  Enter elements: ");
      for(i=0;i<n;i++){
            scanf("%d", a+i);
      }
      for(i=n-1;i>=0;i--){
            if(a[i]%2==0){
              sum+=a[i];

              sum+=a[i];
            }
            else
                printf("");
      }printf("\n  The sum of even number indexes=%d\n", sum);
}
