C Exercises: Display first 10 natural numbers

 

C Exercises: Display first 10 natural numbers

C For Loop: Exercise-1 with Solution

Write a program in C to display the first 10 natural numbers.

Visual Presentation:

Display first 10 natural numbers

Sample Solution:

C Code:

#include <stdio.h>  // Include the standard input/output header file.
int main() {
    int i;

    // Print a message indicating the intention of the program
    printf("The first 10 natural numbers are:\n");

    // Loop through the first 10 natural numbers and print each one
    for (i = 1; i <= 10; i++) {
        printf("%d ", i);
    }

    // Return 0 to indicate successful execution
    return 0;
}

Sample Output:

The first 10 natural numbers are:                                                                               
1 2 3 4 5 6 7 8 9 10

Explanation:

for (i = 1; i <= 10; i++) {
  printf("%d ", i);
}

In the above for loop, the variable i is initialized to 1, and the loop will continue as long as i is less than or equal to 10. In each iteration of the loop, the printf function will print the value of i to the console, followed by a space character.

Finally, the loop will increment the value of i by 1, and the process will repeat until the condition i<=10 is no longer true.

So, when this code runs, it will output the numbers 1 through 10 separated by spaces.

Step wise execution of C program :

  • Green color means line that has just executed
  • Red color means next line to excute
  • Stack : a stack is an abstract data type that serves as a collection of elements.
