C Exercises: Display the sum of first 10 natural numbers
C For Loop: Exercise-2 with Solution
Write a C program to compute the sum of the first 10 natural numbers.
Visual Presentation:

Pseudo code to find the sum of the first 10 natural numbers:
- Initialize a variable "sum" to 0
- Initialize a loop variable "i" to 1
- Repeat the following steps while i <= 10: a. Add i to the sum variable b. Increment i by 1
- Print the "sum" variable value
Sample Solution:
C Code:
#include <stdio.h>
int main()
{
int j, sum = 0;
printf("The first 10 natural number is :\n");
for (j = 1; j <= 10; j++)
{
sum = sum + j;
printf("%d ",j);
}
printf("\nThe Sum is : %d\n", sum);
}
Sample Output:
The first 10 natural number is : 1 2 3 4 5 6 7 8 9 10 The Sum is : 55
Explanation:
for (j = 1; j <= 10; j++) { sum = sum + j; printf("%d ", j); }
In the above for loop, the variable j is initialized to 1, and the loop will continue as long as j is less than or equal to 10. In each iteration of the loop, the sum variable will add the value of j to itself, and the printf function will print the value of j to the console, followed by a space character.
Finally, the loop will increment the value of j by 1, and the process will repeat until the condition j <= 10 is no longer true.
