Prime number in C: Prime number is a number that is greater than 1 and divided by 1 or itself. In other words, prime numbers can't be divided by other numbers than itself or 1. For example 2, 3, 5, 7, 11, 13, 17, 19, 23.... are the prime numbers.
Prime numbers between 20 and 50 are: 23 29 31 37 41 43 47. In this program, the while loop is iterated ( high-low-1) times. In each iteration, whether low is a prime number or not is checked, and the value of low is incremented by 1 until low is equal to high. Visit this page to learn more about how to check whether a number is prime or not.
Apr 10, 2024 · Algorithm to Find Prime Number Program in C. STEP 1: Take num as input. STEP 2: Initialize a variable temp to 0. STEP 3: Iterate a “for” loop from 2 to num/2. STEP 4: If num is divisible by loop iterator, then increment temp. STEP 5: If the temp is equal to 0, Return “Num IS PRIME”. Else, Return “Num IS NOT PRIME”.
