C Program To Check Prime Number In C Using While While loop logic. method 1 source code: prime number or not. logic: method 1. method 2 source code: prime number or not: divide by 2. logic: method 2. method 3 source code: prime number or not: square root method. logic: method 3. If n is perfectly divisible by i, n is not a prime number. in this case, flag is set to 1, and the loop is terminated using the break statement. notice that we have initialized flag as 0 during the start of our program. so, if n is a prime number after the loop, flag will still be 0. however, if n is a non prime number, flag will be 1.
C Program To Check Prime Number In C Using While A prime number is a natural number greater than 1 and is completely divisible only by 1 and itself. in this article, we will learn how to check whether the given number is a prime number or not in c. examples. input: n = 29 output: yes explanation: 29 has no divisors other than 1 and 29 itself. hence, it is a prime number. input: n = 15 output: no. Start the program. declare the variable num to store the input number, isprime to store the prime status, and i as a counter. read the value of num from the user. initialize isprime to 1 (true). initialize i to 2. enter the while loop with the condition i <= sqrt(num). check if num is divisible by i without a remainder. Prime numbers are numbers that have only 2 factors, 1 and themselves. for example, 2, 3, 5, 7, 11, etc are some of the first prime numbers. here we will see whether a number can be expressed as the sum of two prime numbers using a c program. example input: 7output: yesexplanation: 7 can be expressed as sum of 2 and 5 which are prime input: 11output. Prime number: a prime number is a number greater than 1 and which is only divisible by 1 and the number itself. for example, 13 is a prime number as it is divisible by 1 and itself, but 4 is not a prime number as it can be divided by 2. so, to find if a number if prime or not, we can check is number is divisible by any number from 2 to n, if it.

Approach to determine whether the number is prime or not using for loop: first, we declare an integer number. initialize its value from the user using scanf. now we are using for loop to divide that number from all those below that number and check the remainder. use the if statement to check the remainder. Method 1: c program to check whether a number is prime or not using for loop. in this method, we directly check whether the number is prime or not in the main function by using a for loop. we divide the given number, say n, by all possible divisors which are greater than 1 and less the number.
