The if
statement is a fundamental control structure in C programming. It allows for conditional execution of code blocks based on specified conditions.
The basic syntax of an if
statement in C is:
if (condition) {
// code to be executed if condition is true
}
The if
statement enables programmers to create decision-making logic in their code. It evaluates a condition and executes a block of code only if that condition is true.
Here are two simple examples demonstrating the use of if
statements in C:
#include <stdio.h>
int main() {
int number = 10;
if (number > 0) {
printf("The number is positive.\n");
}
return 0;
}
#include <stdio.h>
int main() {
int a = 5, b = 7;
if (a < b) {
printf("%d is less than %d\n", a, b);
}
return 0;
}
if
statement must be enclosed in parentheses.When working with if
