Question

4. Write a C program that will perform the following: a. In the main program enter 2 integer numbers. If the first number is less than the second number call the function happy(). Otherwise give a warning message that the function is not performed. b. Define a function happy() that will request from the user to enter 10 integer numbers to one dimensional array A. The function will find and return how many numbers are above 5.

Answer 1

Screenshot of code:

#include <stdio.h> int happy() { // declare array A[] to save user Input // declare and initialize count as o to save number of integers above 5 int A[10], count = 0; // print message to input 10 numbers printf("Input 10 integers: \n"); // start a for Loop to iterate through every index of A[] for(int i = 0; i <10; i++) { // save user input to A[i] scanf("%d", &A[i]); // check whether current input element is > 5 or not if(A[i]>5) // if input > 5, increment count count = count + 1; } // return count of integers above 5 return count; سها int main() { // declare nl and n2 to save first and second Numbers // count to save return value of happy() int ni, n2, count; // take two integers as input from user printf("Enter Two Integer Numbers: "); scanf("%d%d", &n1, &n2); // compare two numbers user gave if(n1<n2){ // if nl<n2 call happy and print it's return value count = happy(); printf("Number of integers above 5: %d", count); } else // otherwise print warning message print("happy() function is not performed"); return ; }

Sample Outputs:

Enter Two Integer Numbers: 5 6 Input 10 integers: 1 2 3 4 5 6 7 8 9 10 Number of integers above 5: 5

Enter Two Integer Numbers: 6 5 happy() function is not performed

Code to Copy:

#include <stdio.h>

int happy()

{

    // declare array A[] to save user Input

    // declare and initialize count as 0 to save number of integers above 5

    int A[10], count = 0;

    // print message to input 10 numbers

    printf("Input 10 integers:\n");

    // start a for loop to iterate through every index of A[]

    for(int i = 0; i < 10; i++)

    {

        // save user input to A[i]

        scanf("%d", &A[i]);

        // check whether current input element is > 5 or not

        if(A[i]>5)

            // if input > 5, increment count

            count = count + 1;

    }

    // return count of integers above 5

    return count;

}

int main()

{

    // declare n1 and n2 to save first and second Numbers

    // count to save return value of happy()

    int n1, n2, count;

    // take two integers as input from user

    printf("Enter Two Integer Numbers: ");

    scanf("%d%d", &n1, &n2);

    // compare two numbers user gave

    if(n1<n2){

        // if n1<n2 call happy() and print it's return value

        count = happy();

        printf("Number of integers above 5: %d", count);

    }

    else

        // otherwise print warning message

        printf("happy() function is not performed");

    return 0;
