c programming loop code example

Example 2: for loop in c

int i;
for (i = 0; i < n; ++i) { // n is the number of iterations
	// Code here
}

Example 3: for loop in c

// Program to calculate the sum of first n natural numbers
// Positive integers 1,2,3...n are known as natural numbers

#include 
int main()
{
    int num, count, sum = 0;

    printf("Enter a positive integer: ");
    scanf("%d", &num);

    // for loop terminates when num is less than count
    for(count = 1; count <= num; ++count)
    {
        sum += count;
    }

    printf("Sum = %d", sum);

    return 0;
}

Example 4: c make loop

// Print numbers from 1 to 5

#include 
int main()
{
    int i = 1;
    
    while (i <= 5)
    {
        printf("%d\n", i);
        ++i;
    }

    return 0;
}
