Conditional instruction execution is a fundamental necessity for any computer program, and the if statement in C serves as its primary conditional construct.
Syntax
if (condition) {
// block of code to be executed if the condition is true
}Example
Run Code#include
int main() {
int number;
printf("Enter an integer: ");
scanf("%d", &number);
if (number > 0) {
printf("The number is positive.\n");
}
printf("This message is always displayed.\n");
return 0;
}
