c code for loop code example

Example 1: loops in c

// Print numbers from 1 to 10
#include <stdio.h>

int main() {
  int i;

  for (i = 1; i < 11; ++i)
  {
    printf("%d ", i);
  }
  return 0;
}

Example 2: for loop c

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

Example 3: for loop in c

//Sample for loop in c
//Prints the contents of the array in new lines
#include <stdio.h>
int main(){
	int a, b[5] = {2, 4, 5, 7, 9};
  for (a = 0; a<5; a++){
    printf("%d\n", b[a]);
  }
  
      
}

Example 4: 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 <stdio.h>
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;
}
