In programming, it is often necessary to find the number of integers divisible by a certain number. In this program, we will write a C program that prompts the user to enter a list of integers, counts the number of integers that are divisible by 10, and prints the result.

**Problem Statement**

The problem statement is to write a C program that prompts the user to enter a list of integers, counts the number of integers that are divisible by 10, and prints the result.

**Solution**

Here is the C program to find the number of integers divisible by 10

#include <stdio.h> int main() { int n, count = 0; printf("Enter the number of integers: "); scanf("%d", &n); int numbers[n]; for (int i = 0; i < n; i++) { printf("Enter integer #%d: ", i + 1); scanf("%d", &numbers[i]); if (numbers[i] % 10 == 0) { count++; } } printf("\nThe number of integers divisible by 10 is: %d\n", count); return 0; }

**Output**

**Explanation**

First, we include the `stdio.h`

header file which is used for input/output functions. Then, we define the `main()`

function as the starting point of our program.

We declare an integer variable `n`

which will be used to store the number of integers entered by the user. We also declare an integer variable `count`

which will be used to count the number of integers divisible by 10.

Next, we prompt the user to enter the number of integers using the `printf()`

function. The `scanf()`

function is used to read in the number entered by the user. The first parameter to `scanf()`

is the format string “%d” which specifies that the input should be read in as an integer. The second parameter is the address of the `n`

variable where the input should be stored.

We then declare an array `numbers`

of size `n`

to store the integers entered by the user.

We use a `for`

loop to iterate through the array and prompt the user to enter each integer. The `scanf()`

function is used to read in the integer entered by the user. The first parameter to `scanf()`

is the format string “%d” which specifies that the input should be read in as an integer. The second parameter is the address of the `numbers[i]`

variable where the input should be stored.

We then use an `if`

statement to determine whether the integer is divisible by 10. If the integer is divisible by 10, we increment the `count`

variable by 1.

Finally, we print the number of integers divisible by 10 using the `printf()`

function.

**Conclusion**

In this tutorial, we learned how to write a C program to find the number of integers divisible by 10. We used a `for`

loop to iterate through the array of integers entered by the user, and we used an `if`

statement to determine whether each integer is divisible by 10. We then incremented the `count`

variable for each integer divisible by 10 and printed the result using the `printf()`

function.
