User Authentication: When building a login system, “if-else” statements are invaluable for verifying user credentials. Here’s a simplified example: char username[] = "user123"; char password[] = "pass456"; char input_username[20]; char input_password[20]; printf("Enter username: "); ...
If (year % 4 == 0 && (year % 400 == 0 || year % 100 != 0)){ printf("%d is a leap year", year); } else{ printf("%d is not a leap year", year); } With nested if statements in C, we can write structured and multi-level decision-making algorithms. They simplify coding...
On my computer the pipe shares its key with \. Keep in mind that OR will be evaluated after AND. It is possible to combine several boolean operators in a single statement; often you will find doing so to be of great value when creating complex expressions for if statements. What is !
if (i == 5) { continue; // Skip the remaining statements in this iteration } printf("%d ", i); } return 0; } In this example, when the value of “i” is 5, the “continue” statement is encountered. This causes the program to skip the remaining statements within the current ite...
However, if the test expression is evaluated to true, statements inside the body of the for loop are executed, and the update expression is updated. Again the test expression is evaluated. This process goes on until the test expression is false. When the test expression is false, the loop ...
Here, as long as the condition within the parenthesis stands true, all the statements inside the loop are executed. Which means that the while loop will be executed thrice. To be noted, if we do not write the condition in which we increment the value ofcount, the loop will become an in...

If the condition is true then the control enters the body of the while Loop and runs the statements inside the while loop. As the control comes to the end of While Loop, the control again goes to While Loop and the condition is checked again and if the condition is true this time, ...

The initializer is used to initialize the loop control variable. The condition is checked each time before execution of the statements. If the condition evaluates to true, then the statements are executed. And if the condition evaluates to false, then execution of the statements is terminated. Th...
