In this tutorial, you will learn about if statement (including if...else and nested if..else) in C programming with the help of examples.

Dec 23, 2024 · The if else in C is an extension of the if statement which not only allows the program to execute one block of code if a condition is true, but also a different block if the condition is false. This enables making decisions with two possible outcomes.

Use the else if statement to specify a new condition if the first condition is false. printf ("Good morning."); printf ("Good day."); printf ("Good evening."); // Outputs "Good evening." In the example above, time (22) is greater than 10, so the first condition is false.

Jun 13, 2022 · In this article, you will learn all about the if statement – its syntax and examples of how to use it so you can understand how it works. You will also learn about the if else statement – that is the else statement that is added to the if statement for additional program flexibility.

The if-else statement is one of the frequently used decision-making statements in C. The if-else statement offers an alternative path when the condition isn't met. The else keyword helps you to provide an alternative course of action to be taken when the Boolean expression in the if statement turns out to be false.

Aug 8, 2024 · In ‘C’ programming conditional statements are possible with the help of the following two constructs: 1. If statement. 2. If-else statement. It is also called as branching as a program decides which statement to execute based on the result of the evaluated condition.

Jan 23, 2013 · if (expression1) { Statements; if (expression2) { Statements; } else { Statements; } } Given below is basic program using nested if conditions. #include <stdio.h> int main(int argc, char *argv[]) { int i = 5; int *ptr = &i; int **double_ptr = &ptr; if (double_ptr != NULL) { if (ptr != NULL) { printf ("Now safe to access pointer, ptr contains %d ...

May 24, 2015 · In this exercise we will focus to control program flow using if...else statements. Below is the list of if else programming exercises and solutions in C.

Feb 17, 2025 · With if-else in C language, developers can write dynamic programs that adapt to user inputs or real-world data. From validating user credentials to assigning grades based on marks, the if-else construct is widely used in problem-solving. In this post, we’ll explore how if-else works, its syntax, and practical examples.

In this C Tutorial, we learned what an If-Else statement is in C programming language, how its execution happens, and how it works with an example program. So, in C if-else statement, we have an if block followed by else block. If the condition is true, if block is executed, and if the condition is false, else.
