C Exercises: Read and print the elements of an array of length 7 replacing some values

C Basic Declarations and Expressions: Exercise-48 with Solution

Write a C program to read and print the elements of an array of length 7, before print replace every negative number, zero with 100.

Pictorial Presentation:

Sample Solution:

C Code:

#include <stdio.h>
int main() {
	int n[5], i, x;
	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;
		}
	}
	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
