Comparison operators in C++ are used to compare two values or variables. They return a boolean result:<\/p>\n\n\n\n
true<\/code> (1)<\/li>\n\n\n\nfalse<\/code> (0)<\/li>\n<\/ul>\n\n\n\nThese operators are mainly used in conditions and decision-making statements.<\/p>\n\n\n\n
What are Comparison Operators?<\/h2>\n\n\n\n
Comparison operators check relationships between values such as:<\/p>\n\n\n\n
\n- Equal to<\/li>\n\n\n\n
- Greater than<\/li>\n\n\n\n
- Less than<\/li>\n<\/ul>\n\n\n\n
They help programs make decisions based on conditions.<\/p>\n\n\n\n
Types of Comparison Operators in C++<\/h2>\n\n\n\nOperator<\/th> Meaning<\/th><\/tr><\/thead> ==<\/code><\/td>Equal to<\/td><\/tr> !=<\/code><\/td>Not equal to<\/td><\/tr> ><\/code><\/td>Greater than<\/td><\/tr> <<\/code><\/td>Less than<\/td><\/tr> >=<\/code><\/td>Greater than or equal to<\/td><\/tr> <=<\/code><\/td>Less than or equal to<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nEqual To Operator (==)<\/h2>\n\n\n\n
Checks if two values are equal.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\n#include <iostream>
using namespace std;
int main() {
int a = 10;
int b = 10;
cout << (a == b);
return 0;
}<\/code><\/pre>\n\n\n\nOutput<\/h2>\n\n\n\n1<\/code><\/pre>\n\n\n\nNot Equal To Operator (!=)<\/h2>\n\n\n\n
Checks if two values are different.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\ncout << (10 != 5);<\/code><\/pre>\n\n\n\nGreater Than Operator (>)<\/h2>\n\n\n\n
Checks if the left value is greater.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\ncout << (10 > 5);<\/code><\/pre>\n\n\n\nLess Than Operator (<)<\/h2>\n\n\n\n
Checks if the left value is smaller.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\ncout << (5 < 10);<\/code><\/pre>\n\n\n\nGreater Than or Equal To (>=)<\/h2>\n\n\n\n
Checks if value is greater or equal.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\ncout << (10 >= 10);<\/code><\/pre>\n\n\n\nLess Than or Equal To (<=)<\/h2>\n\n\n\n
Checks if value is smaller or equal.<\/p>\n\n\n\n
Example<\/h3>\n\n\n\ncout << (5 <= 10);<\/code><\/pre>\n\n\n\nComplete Example Program<\/h2>\n\n\n\n#include <iostream>
using namespace std;
int main() {
int a = 10;
int b = 5;
cout << (a == b) << endl;
cout << (a != b) << endl;
cout << (a > b) << endl;
cout << (a < b) << endl;
cout << (a >= b) << endl;
cout << (a <= b) << endl;
return 0;
}<\/code><\/pre>\n\n\n\nOutput<\/h2>\n\n\n\n0

cout << \"Adult\";
}<\/code><\/pre>\n\n\n\nImportant Points<\/h2>\n\n\n\n\n- Comparison operators return boolean values<\/li>\n\n\n\n
true<\/code> is displayed as 1<\/code><\/li>\n\n\n\nfalse<\/code> is displayed as 0<\/code><\/li>\n\n\n\n- They are commonly used in
if<\/code>, while<\/code>, and loops<\/li>\n<\/ul>\n\n\n\nWhy Comparison Operators are Important<\/h2>\n\n\n\n
They are important because they:<\/p>\n\n\n\n
\n- Help in decision-making<\/li>\n\n\n\n
- Control program flow<\/li>\n\n\n\n
- Compare values efficiently<\/li>\n\n\n\n
- Are used in conditions and loops<\/li>\n<\/ul>\n\n\n\n
Real-Life Example<\/h2>\n\n\n\n
Comparison operators are used in:<\/p>\n\n\n\n
<\/strong> <\/p> <\/div> <\/div>\n\n\n\n
\n- Login systems<\/li>\n\n\n\n
- Age verification<\/li>\n\n\n\n
- Exam result checking<\/li>\n\n\n\n
- Banking conditions<\/li>\n\n\n\n
- Game logic<\/li>\n<\/ul>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
Comparison operators in C++ are essential for checking conditions and making decisions in programs. They compare values and return true or false results, helping create logical and interactive applications.<\/p>\n\n\n
