C Practice Exercise

Write a C program that reads and prints the elements of an array of length 7. Before printing, replace every negative number, zero, with 100.

Pictorial Presentation:

Sample Solution:

C Code:

#include <stdio.h>
int main() {
    int n[5], i, x;
    
    // Input the 5 members of the array
    printf("Input the 5 members of the array:\n");
    for(i = 0; i < 5; i++) {
        scanf("%d", &x);
        if(x > 0) {
            n[i] = x;
        } else {
            n[i] = 100;
        }
    }
    
    // Print the array values
    printf("Array values are: \n");
    for(i = 0; i < 5; i++) {
        printf("n[%d] = %d\n", i, n[i]);
    }
    
    return 0;
}

Sample Output:

Input the 5 members of the array:                                      
25                                                                     
45                                                                     
35                                                                     
65                                                                     
15                                                                     
Array values are:                                                      
n[0] = 25                                                              
n[1] = 45                                                              
n[2] = 35                                                              
n[3] = 65                                                              
n[4] = 15
