Explanation:

This C program prints the numbers from 1 to 100. Here’s a step-by-step explanation of the code:

Header File:

• The program includes the standard C library header <stdio.h>. This header is required for input and output operations.

Main Function:

• The main function is the entry point of the program, where the execution starts.

Variable Declaration:

• The program declares an integer variable ‘i’. This variable is used as a loop counter to iterate through the numbers from 1 to 100.

For Loop:

The program utilizes a for loop to repeatedly execute a block of code. The loop is structured as follows:

• Initialization: i = 1 – The loop counter ‘i’ is initialized to 1 when the loop begins.
• Condition: i <= 100 – The loop continues as long as ‘i’ is less than or equal to 100.
• Increment: i++ – After each iteration, ‘i’ is incremented by 1.

Printing Numbers:

• Inside the loop, the program uses printf to display the value of ‘i’ followed by a newline character (\n). This will print the current value of ‘i’ on the screen and move to the next line.

Loop Iteration:

• The loop continues to execute, incrementing ‘i’ in each iteration. It prints the numbers from 1 to 100, one number per line.

End of Program:

• Once ‘i’ exceeds 100 (after printing 100), the loop terminates, and the program reaches the end of the main function, concluding the program’s execution.
• In summary, this code uses a for loop to iterate through the numbers from 1 to 100, printing each number on a separate line. This generates a list of integers from 1 to 100.
