+#include <iostream>
+#include <cmath>
+
+bool isPrime(int n) {
+    if (n <= 1) return false;
+    for (int i = 2; i <= sqrt(n); i++) {

+
+## Explanation
+This C program checks if a given nember is a prime number.It uses a function isPrime() to then determine whether a number is a prime number and the gives the output.
+
+This C++ program checks when a given number is a prime number by using the simple function isPrime() and the gives an out. It does so by using the <iostream> which is a library for input/output and the <cmath> for calculation.
+
+
+### DIFFERENCES
+
+1. **Syntax**:
+   - In C it uses a standard input-output library which gives us the ability to use functions such as print() to give output.
+   - In C++ it uses a standard input-output stream library which makes us be able to use std::cout and std::endl to display the output.
+
+2. **How they carry out calculation**:
+   -  C uses the bool data type to which provides true and false values for logical operation whilst the C++ use a math library to do mathematical functions such as sqrt() that calculkates square root numbers.
+
+
+
+### SIMILARITIES
+
+1. **Codes**: 
+   - Both C and C++ use the function if (n <= 1) return false to determine if the number is a prime number.
+   - They both have the ability to do loop for Checking Divisibility.
+   - the function return true; is use by both programs to return true if No Divisors found.
