Question

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a space, including the last one

Answer 1

Answer:

Following is the program in C language :

#include <stdio.h> // header file

#define n 5 //  macro

int main() main function

{

   int a[n],k1; // variable and array declaration

   printf("Enter the element:\n");

   for(k1=0;k1<n;++k1) //iterating the loop

   {

       scanf("%d",&a[k1]);//Read the values by user

   }

   printf("Output in Reverse Order:\n");

   for(k1=n-1;k1>=0;--k1)//iterating the loop

   {

   printf(" %d ",a[k1]); //Display the values

   }

   return 0;

}

Output:

Enter the element:

4

3

45

67

89

Output in Reverse Order: 89 67 45 3 4

Explanation:

Following is the description of the program

• Define a macro "n" with value 5 after the header file.

• Declared an array "a" and defined the size of that array by macro i.e "n".

• Read the value by the user by using scanf statement in the array "a"

• Finally In the last for loop display the values of array "a" by space.
