For vs While Loop in C

For Loop in C 

 The for loop in C is used to execute a block of code repeatedly until a specified condition is met.

 In C, the for loop starts with setting up then checks a condition, and finally changes something each time it runs, lasting until the condition is no longer true.

Syntax of For Loop in C:

		
for (initialization; condition; increment/decrement) {
    // Code to be executed
}

Example:

The sum of Numbers using for Loop:

 // Program for For loop in C
#include<stdio.h> 

int main() {
    int sum = 0, i;
    for (i = 1; i <= 5; ++i) {
        sum += i;
    }
    printf("Sum of numbers from 1 to 5: %d\n", sum);
    return 0;
}	

Output:

Sum of numbers from 1 to 5: 15

While Loop in C 

 The while loop in C is used to execute a block of code repeatedly as long as a specified condition is true.

 Before executing the code block, the loop assesses whether the condition is met.

Syntax of while loop in C:

		
while (condition) {
    // Code to be executed
}

Example:

The sum of Numbers using while Loop:

// Program for while loop
#include<stdio.h>

int main() {
    int sum = 0, i = 1;
    while (i <= 5) {
        sum += i;
        ++i;
    }
    printf("Sum of numbers from 1 to 5: %d\n", sum);
    return 0;
}	

Output:

Sum of numbers from 1 to 5: 15

Both for and while loops serve the purpose of repeating a block of code, and the choice between them depends on the specific requirements of the program and the nature of the iteration.

Difference between For and While loop  

Aspect	For Loop	While Loop
Initialization	Initialization within the loop	Initialization outside the loop
Condition Check	Checked at the beginning of each loop	Checked at the beginning of each loop
Increment	Included in the loop	Excluded from the loop
Use Cases	Definite iterations	Indefinite iterations
Statement Format	for (initialization; condition; increment/decrement)	while (condition)
