for Loop in C Programming Language

In C programming language, the for loop is used to execute a block of code repeatedly. It is a widely used looping construct with a compact syntax.

Syntax of the for Loop

The syntax of the for loop in C programming language is as follows:

for (initialize; condition; increment/decrement) {
    // code block to be executed
}

Here,

• initialize : It is the initialization block where the initialization of the loop counter takes place. It is executed only once, before the beginning of the loop.
• condition : It defines the condition for the loop. If the condition is true, the code block inside the loop is executed. If it is false, the loop terminates.
• increment/decrement : It is the block where the loop counter is incremented or decremented after the execution of the code block.

Example

Here is an example that demonstrates the use of the for loop in C programming language.

#include <stdio.h>

int main() {
   int i;
   for (i = 1; i <= 10; i++) {
      printf("%d ", i);
   }
   return 0;
}

In the above example, the variable i is initialized to 1 in the first block of the for loop. The loop continues as long as i is less than or equal to 10. After each iteration, the value of i is incremented by 1. The output of the above program would be:

1 2 3 4 5 6 7 8 9 10

Conclusion

The for loop is a common construct in C programming language. It allows for the execution of a block of code repeatedly, based on a specific condition. Its syntax is easy to understand and it is often used in various programming applications.
