C Practice Exercise

Write a C program that reads 5 numbers and sums all odd values between them.

Pictorial Presentation:

C Code:

#include <stdio.h>
int main() {
    int j, numbers[5], total=0; // Declare variables for loop counter, an array of numbers, and total
    
    // Prompt user for five numbers and store them in the array
    printf("\nInput the first number: "); 
    scanf("%d", &numbers[0]);
    printf("\nInput the second number: "); 
    scanf("%d", &numbers[1]);
    printf("\nInput the third number: "); 
    scanf("%d", &numbers[2]);
    printf("\nInput the fourth number: "); 
    scanf("%d", &numbers[3]);
    printf("\nInput the fifth number: "); 
    scanf("%d", &numbers[4]);
    
    // Loop through the numbers to find and sum the odd ones
    for(j = 0; j < 5; j++) {
        if((numbers[j]%2) != 0) 
        {
            total += numbers[j];
        }   
    }
    
    // Print the sum of odd values
    printf("\nSum of all odd values: %d", total);
    printf("\n");
    
    return 0;
}

Sample Output:

Input the first number: 11                                             
                                                                       
Input the second number: 17                                            
                                                                       
Input the third number: 13                                             
                                                                       
Input the fourth number: 12                                            
                                                                       
Input the fifth number: 5                                              
                                                                       
Sum of all odd values: 46

C Programming Code Editor:

Previous: Write a C program that reads an integer and check the specified range where it belongs. Print an error message if the number is negative and greater than 80.
Specified Range: [0, 20], [21, 40], [41, 60], [61, 80]
Next: Write a C program that reads three floating values and check if it is possible to make a triangle with them. Also calculate the perimeter of the triangle if the said values are valid.
