What is the output of C Program.?#include<stdio.h>int main(){int a=4;while(a>=1){printf("hello ");break;}return 0;}

The output of the C program will be "hello ".

Here's the step by step explanation:

1. The program starts with the inclusion of the standard input-output library using #include<stdio.h>.

2. The main function is declared with int main(). This is the entry point of the program.

3. Inside the main function, an integer variable a is declared and initialized with the value 4.

4. Then, a while loop is started with the condition a>=1. Since a is 4, which is greater than 1, the condition is true.

5. Inside the while loop, the printf function is used to print the string "hello " to the console.

6. Immediately after the printf function, there is a break statement. This statement causes the program to exit the loop immediately, regardless of the loop condition.

7. After the loop, the program returns 0 and ends.

So, even though the loop condition is true for a values 4, 3, 2, and 1, the loop only executes once because of the break statement. That's why "hello " is printed only once.
