Syntax of if...else if (testExpression) { // codes inside the body of if } else { // codes inside the body of else } If test expression is true, codes inside the body of if statement is executed and, codes inside the body of else statement is skipped. If test expression is false, codes inside the body of else statement is executed and, codes inside the body of if statement is skipped. // Program to check whether an integer entered by the user is odd or even #include <stdio.h> int main() { int number; printf("Enter an integer: "); scanf("%d",&number); // True if remainder is 0 if( number%2 == 0 ) printf("%d is an even integer.",number); else printf("%d is an odd integer.",number); return 0; }
