In computer programming, we use the if...else statement to run one block of code under certain conditions and another block of code under different conditions. For example, assigning grades (A, B, C) based on marks obtained by a student.

The if Statement Use the if statement to specify a block of C++ code to be executed if a condition is true.

C++ supports two basic kinds of conditionals: if statements (which we introduced in lesson 4.10 -- Introduction to if statements, and will talk …

C++ if Statements control the flow of the program based on conditions. If the expression evaluates to true, it executes certain statements within the if block; Otherwise, execution will get skipped. It is the simplest way to modify the control flow in a C++ program. This tutorial will teach you how to use if Statements in C++.

Jun 24, 2021 · If expression compares not equal to the integer zero, statement-true is executed. In the form (2), if expression compares equal to the integer zero, statement_false is executed.
