The Else If Statement in C is very useful when we have to check several conditions. We can also use the Nested If statement to achieve the same but as the number of conditions increase, code complexity will also increase. Let us see the syntax of the Else if statement:
Else If Statement in C Language Syntax
The syntax of the Else If statement in C Programming is as follows:
|
1 2 3 4 5 6 7 8 9 10 11 |
if (condition 1) statements 1 else if (condition 2) statements 2 else if (condition 3) statements 3 ........... else if (condition n) statements n else default statements |
There will be some situations where condition 1, condition 2 is TRUE, for example:
x= 20, y=10
Condition 1: x > y //TRUE
Condition 2: x != y //TRUE
In these situations, statements under the Condition 1 will be executed because ELSE IF conditions will only be executed if its previous IF or ELSE IF statement fails.
Flow Chart for Else If Statement in C Programming
Else If Statement in C Programming Example
In this program, User is asked to enter his total 6 subject marks. Using Else if statement in c we are going to calculate whether he is eligible for scholarship or not

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
/* Example for Else If Statement in C Language */ #include <stdio.h> int main() { int Totalmarks; //Imagine you have 6 subjects and Grand total is 600 printf("Please Enter your Total Marks\n" ); scanf( "%d", &Totalmarks ); if (Totalmarks >= 540) { printf("You are eligible for Full Scholarship\n"); printf("Congratulations\n"); } else if (Totalmarks >= 480) { printf("You are eligible for 50 Percent Scholarship\n"); printf("Congratulations\n"); } else if (Totalmarks >= 400) { printf("You are eligible for 10 Percent Scholarship\n"); printf("Congratulations\n"); } else { printf("You are Not eligible for Scholarship\n"); printf("We are really Sorry for You\n"); } } |
OUTPUT 1: We are going to enter Totalmarks = 570. Here first If condition is TRUE
OUTPUT 2: We are going to enter Totalmarks = 490 means first IF condition is FALSE. It will check the else if (Totalmarks >= 480), which is TRUE so it will print the statements inside this block. Although else if (Totalmarks >= 400) condition is TRUE, but it won’t check this condition.
OUTPUT 3: We are going to enter Totalmarks = 401 means first IF condition, else if (Totalmarks >= 480) are FALSE. So, It will check the else if (Totalmarks >= 401), which is TRUE so it will print the statements inside this block.
OUTPUT 4: We are going to enter Totalmarks = 380 means all the IF conditions Fail. So, It will print the statements inside the else block.
