If else Statement in C programming language, when we need to execute a block of statements that too when a particular condition is met or not met that situation is known as decision making. In C we represent true with a non-zero integer and false with zero. The if-else different conditions to be performed. In C programming, the decision-making process is used to specify certain orders in which statements … the default is executed instead of another row. statements specified in the if block will be executed in the if-else-if ladder The condition enclosed in if statement decides the sequence of execution of instruction. if statement is used for branching when a single condition is to be checked.

The ability to control the flow of your program, letting it make decisions on what code to execute, is valuable to the programmer. The syntax of an 'if' statement in C programming language is − if (boolean_expression) { /* statement (s) will execute if the boolean expression is true */ } If the Boolean expression evaluates to true, then the block of code inside the 'if' statement will be executed. The programming flow Chart behind this Else If Statement in C Programming is as shown below. If Else Statement prints different statements based on the expression result (TRUE, FALSE). I want to only execute a printf statement if a either 1,2,4 or 6 AND b = 8 and c = 10, can I put all these The if-else statement in C is based on some particular conditions to perform the operations. Three types of selection statements exist in C: if ( expression ) statement In this type of if-statement, the sub-statement will only be executed iff the expression is non-zero. In the C programming language, first evaluates the test expression inside the parenthesis of if part, when the test expression is true, the flow of control enters the codes inside the body of if part and executes body part statement. The if statement in C programming language is used to execute a block of code only if condition is true. Depending on Welcome, what is PHP If Else statement in Hindi?

Thanks again!! Also we’ll cover switch statement. Once an else statement gets failed there are times when the next execution of statement wants to return a true statement, there we need nesting of if statement to make the entire flow of code in a semantic order. C if.else Statement In this tutorial, you will learn about if statement (including if.else and The condition following the keyword if is always enclosed within a pair of parentheses. in if block is executed. Here we must remember that if block can’t be executed simultaneously, then otherwise. When the above code is compiled and executed, it produces the following result −.

Also notice the condition in the parenthesis of the if statement: n == 3. True is always a non-zero value, and false is a value that contains zero. C programming language assumes any non-zero and non-null values as true and if it is either zero or null, then it is assumed as false value.
