If Else Statement in C Programming Language
If Else Statement in C
The if-else statement is used to perform two operations for a single condition. The if-else statement is an extension to the if statement using which, we can perform two different operations, i.e., one is for the correctness of that condition, and the other is for the incorrectness of the condition. Here, we must notice that if and else block cannot be executed simiulteneously. Using if-else statement is always preferable since it always invokes an otherwise case with every if condition.
Syntax for if-else Statement in C
if (test expression) {
// run code if test expression is true
}
else {
// run code if test expression is false
}
/* if else statement in C language */
// Check whether an integer is odd or even
#include <stdio.h>
int main() {
int number;
printf("Enter an integer: ");
scanf("%d", &number);
// True if the remainder is 0
if (number%2 == 0) {
printf("%d is an even integer.",number);
}
else {
printf("%d is an odd integer.",number);
}
return 0;
}
C Coding calculate the Fibonacci Numbers in the series. First two numbers in the Fibonacci sequence are 0, 1 & each subsequent number is the sum of the previous 2. Fn = Fn-1 + Fn-2
Program to find HCF of a given number using recursion. Programming code using recursion finds the HCF of 2 entered integers. The 'HCF' stands for Highest Common Factor. Enter the
