Pruebe el siguiente ejemplo para comprender todos los operadores relacionales disponibles en C ++.
Copie y pegue el siguiente programa C ++ en el archivo test.cpp y compile y ejecute este programa.
#include <iostream>
using namespace std;
main() {
int a = 21;
int b = 10;
int c ;
if( a == b ) {
cout << "Line 1 - a is equal to b" << endl ;
} else {
cout << "Line 1 - a is not equal to b" << endl ;
}
if( a < b ) {
cout << "Line 2 - a is less than b" << endl ;
} else {
cout << "Line 2 - a is not less than b" << endl ;
}
if( a > b ) {
cout << "Line 3 - a is greater than b" << endl ;
} else {
cout << "Line 3 - a is not greater than b" << endl ;
}
/* Let's change the values of a and b */
a = 5;
b = 20;
if( a <= b ) {
cout << "Line 4 - a is either less than \ or equal to b" << endl ;
}
if( b >= a ) {
cout << "Line 5 - b is either greater than \ or equal to b" << endl ;
}
return 0;
}
Cuando se compila y ejecuta el código anterior, produce el siguiente resultado:
Line 1 - a is not equal to b
Line 2 - a is not less than b
Line 3 - a is greater than b
Line 4 - a is either less than or euqal to b
Line 5 - b is either greater than or equal to b
