# Operators in C++

C++ operators are a special type of functions or symbols that take one or more than one arguments and create a new value or in other words used to perform various logical and mathematical manipulations or calculations.

They act as the foundation of C++ programming, languages such as c or c++ is incomplete without operators. C++ consists of a list of operators that are divided into groups such as:

- Arithmetic Operators (+,-,*, /, %)
- Unary operator(++, –)
- Assignment Operator(=,+=)
- Relational Operators (<,>,>=, <=,! = ,==)
- Ternary operators (?:)
- Bitwise Operators(&,<<,>>,~,^,|)
- Logical Operators(&&, ||)
- Misc Operator (sizeof(),*,?:,&,)
- Ternary Operator

**List of Operators present in C++**

Operators | Syntax |
---|---|

Assignment operators | P=r |

Subtraction | P-r |

Addition | P+r |

Division | p/r |

Multiplication | p*r |

Unary minus | -r |

Unary plus | +r |

Modulo | p%r |

Decrement operator (pre, post) | --r, r-- |

Increment operator (pre, post) | ++r, r++ |

!ERROR! unexpected operator '=' | p == r |

Not equal to | p != r |

Less than | < |

Greater than | > |

Less than equal to | <= |

Greater than equal to | >= |

Logical or | p || r |

Logical not | !p |

Addition Assignment | p += q |

Scope Resolution operators | p :: q |

Division Assignment | P /= q |

Logical and | p && q |

Comma | p,r |

**Following is the simple program on operators**

#include<iostream> // Main Function using namespace std; int main () { // Variable Declaration int p = 38; int r = 20; int z = 40; int q = 60; int result; cout << " Operators Example Program \n"; result = p - r; // subtraction ( Subtraction or unary minus Arithmetic Operator) cout <<"\np - r = "<<result; result = r * z; // multiplication ( Multiplication Arithmetic Operator) cout <<"\nr * z = "<< result; result = p / z; // division ( Division Arithmetic Operator) cout <<"\na / c = "<< result; result = p + r * z; // precedence ( Addition or unary plus Arithmetic Operator) cout <<"\np + r * z = "<< result; cout <<"\np * r + z * q = "<< p * r + z * q; // Mixed return 0; }

**Result:**

Operators Example Program

p – r = 18

r * z = 800

a / c = 0

p + r * z = 838

p * r + z * q = 3160
