Read this: The % is called the mod operator, it returns the remainder of a division. e.g. 13%5 = 13 / 5 = 2 (quotient) + 3 (remainder) = 3 17 %5= 17 / 5 = 3 (quotient) + 2 (remainder) = 2 56 % 13 = 4 (quotient) + 4 (remainder) = 4 We can check if a number is even or odd by using % (mod) operator if a number is even the remainder with 2 will be zero for odd number it will be a non zero number 3 %2 = 1 (3 is odd) 7 %2 = 1 (7 is odd) 6% 2 = 0 (6 is even) (have a look at the following program) Program-02 #include <stdio.h> #include <conio.h> #include <iostream.h> main(void) { int x; cout<<”Enter value for x:”; cin>>x; if( (x%2)==0) cout<<”X is an even integer”<<endl; else cout<<”X is an odd integer”<<endl; getch(); } Program-03 #include <stdio.h> #include <conio.h> #include <iostream.h> main() { int length, width; cout<<”Enter the length of the diagram”<<endl; cin>>length; cout<<”Enter the width of the diagram”<<endl; if(length==width) cout<<”The diagram is a square”<<endl; else cout<<”The diagram is a rectangle”; getch(); } Exercise Extend the program, get length and width of two diagram from the user and check 1) the two diagrams are of same length and same width 2) which of the two diagram is a square and which one is a rectangle Hint: Do it on paper for two diagrams , develop a technique to compare diagrams and then write the program Program-04 (character input) #include <stdio.h> #include <conio.h> #include <iostream.h> main() { char ans; cout<<”Is today your birthday ? (Y/N) : “; cin>>ans; if(ans==’y’ || ans == ‘Y’) cout<<” Happy Birthday To You “<<endl ; else Docsity.com
