In this article, we will learn to generate and display all prime numbers from 1 to N in C programming language. Prime Numbers from 1 to 100. Algorithm. Check every number from 1 to N whether it is prime by using isPrime () function.
Jul 18, 2024 · C Program for Prime Numbers Using While Loop Algorithm to Find Prime Number Program in C. STEP 1: Take num as input. STEP 2: Initialize a variable temp to 0. STEP 3: Initialize the iterator variable loop to 2. STEP 4: Iterate a “while” with the condition, loop <= num/2. STEP 5: If num is divisible by loop iterator, then increment temp.
Prime number program in C language to check whether a number is prime or composite, to print prime numbers. A number is prime if it's divisible only by one and itself. Two is the only even and the smallest prime number. First few prime numbers are 2, 3, 5, 7, 11, 13, 17, ....
