C Practice Exercise

Write a C program to read an array of length 5 and print the position and value of the array elements of value less than 5.

Pictorial Presentation:

Sample Solution:

C Code:

#include <stdio.h>
#define AL 5  // Define the size of the array as 5
#define MAX 5 // Define a maximum value for comparison

int main() {
    float N[AL]; // Declare an array of size 5 to hold floating-point numbers
    int i;
    
    // Prompt for user input
    printf("Input the 5 members of the array:\n");
    
    // Read and store user input into the array
    for(i = 0; i < AL; i++) {
        scanf("%f", &N[i]);
    }
    
    // Iterate through the array and print elements less than MAX
    for(i = 0; i < AL; i++) {
        if(N[i] < MAX) {
            printf("A[%d] = %.1f\n", i, N[i]);
        }
    }
    
    return 0;
}

Sample Output:

Input the 5 members of the array:                                      
15                                                                     
25                                                                     
4                                                                      
35                                                                     
40                                                                     
A[2] = 4.0
