An operator is an symbol that advises the compiler to perform explicit mathematical or logical controls. C++ is wealthy in underlying operators and give the accompanying sorts of operators −
Assume variable A holds 10 and variable B holds 20, then −
| Operator | Description | Example |
|---|---|---|
| + | Adds two operands | A + B will give 30 |
| - | Subtracts second operand from the first | A - B will give -10 |
| * | Multiplies both operands | A * B will give 200 |
| / | Divides numerator by de-numerator | B / A will give 2 |
| % | Modulus Operator and remainder of after an integer division | B % A will give 0 |
| ++ | Increment operator, increases integer value by one | A++ will give 11 |
| -- | Decrement operator, decreases integer value by one | A-- will give 9 |
| Operator | Description | Example |
|---|---|---|
| == | Checks if the values of two operands are equal or not, if yes then condition becomes true. | (A == B> is not true. |
| != | Checks if the values of two operands are equal or not, if values are not equal then condition becomes true. | (A != B> is true. |
| > | Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. | (A > B> is not true. |
| < | Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. | (A < B> is true. |
| >= | Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. | (A >= B> is not true. |
| <= | Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. | (A <= B> is true |
Assume variable A holds 1 and variable B holds 0, then −
| Operator | Description | Example |
|---|---|---|
| && | Called Logical AND operator. In the event that both the operands are non-zero, condition becomes true. | (A && B> is false. |
| || | Called Logical OR Operator. In the event that any of the two operands is non-zero, condition becomes true. | (A || B> is true. |
| ! | Called Logical NOT Operator. Use to switches the logical condition of its operand. In the event that a condition is true, Logical NOT operator will make false. | !(A && B> is true. |
Bitwise operator works on bits and perform bit-by-bit operation. The truth tables for &, |, and ^ are as follows −
| p | q | p & q | p | q | p ^ q |
|---|---|---|---|---|
| 0 | 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 1 | 1 |
| 1 | 1 | 1 | 1 | 0 |
| 1 | 0 | 0 | 1 | 1 |
| Operator | Description | Example |
|---|---|---|
| = | Simple assignment operator, Assigns values from right side operands to left side operand. | C = A + B will allocate worth of A + B into C |
| += | Add AND assignment operator, It adds right operand to the left operand and allot the outcome to left operand. | C += An is identical to C = C + A |
| -= | Subtract AND assignment operator, It takes away right operand from the left operand and allocate the outcome to left operand. | C - = An is comparable to C = C - A |
| *= | Multiply AND assignment operator, It multiplies right operand with the left operand and allocate the outcome to left operand. | C *= An is comparable to C = C * A |
| /= | Divide AND assignment operator, It isolates left operand with the right operand and allocate the outcome to left operand. | C/= An is comparable to C = C |
| %= | Modulus AND assignment operator, It takes modulus utilizing two operands and relegate the outcome to left operand. | C %= An is comparable to C = C % A |
| <<= | Left shift AND assignment operator. | C <<= 2 is same as C = C << 2 |
| >>= | Right shift AND assignment operator. | C >>= 2 is same as C = C >> 2 |
| &= | Bitwise AND assignment operator. | C &= 2 is same as C = C and 2 |
| ^= | Bitwise exclusive OR and assignment operator. | C ^= 2 is same as C = C ^ 2 |
| |= | Bitwise comprehensive OR and assignment operator. | C |= 2 is same as C = C | 2 |
| Sr.No | Operator and Description |
|---|---|
| 1 | sizeof sizeof operator returns the size of a variable. For instance, sizeof(a> , where 'a' is integer, and will bring 4 back. |
| 2 | Condition ? X : Y Condition operator (?> . On the off chance that Condition is valid, it returns value of X in any case returns value of Y. |
| 3 | , Comma operator makes an arrangement of activities be performed. The worth of the whole comma articulation is the value of the last articulation of the comma-isolated list. |
| 4 | . (dat> and - > (arrow> Part operators are utilized to reference individual individuals from classes, structures, and unions. |
| 5 | Cast Casting operators convert one data type to another. For instance, int(2.2000> would bring 2 back. |
| 6 | & Pointer operator and returns the location of a variable. For instance &a; will give real location of the variable. |
| 7 | * Pointer operator * is pointer to a variable. For instance *var; will pointer to a variable var. |
object oriented java :OOP stands for Object-Oriented Programming. Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods.
C++ programming basics C++ is a powerful general-purpose programming language. It can be used to develop operating systems, browsers, games, and so on. C++ supports different ways of programming like procedural, object-oriented, functional, and so on. This makes C++ powerful as well as flexible.
