How to use the exponentiation operator in C language

In C language, the power operator is ^, which is used to calculate the power of a number. Place the base on the left side of the operator and the exponent on the right side. The precedence of this operator is higher than * and /, and lower than the unary operator. The data type of the base and exponent can be any integer type, and the data type of the result is the same as the base. Note that negative exponents generate compiler errors; positive powers of 0 are 0, negative powers raised to odd powers are negative, and negative powers raised to even powers are positive.

The exponentiation operator in C language

In C language, the exponentiation operator is ^, used to calculate the power of a number.

Operator usage

To perform exponentiation, place the base to the left of the operator and the exponent to the right. For example:

int result = 2 ^ 3; // result 为 8

Example

#include <stdio.h>

int main() {
    int base = 5;
    int exponent = 2;

    int result = base ^ exponent;

    printf("结果：%d\n", result); // 输出：25

    return 0;
}

Priority

^ Operators have higher precedence Greater than the * and / operators, but lower than the unary operators (such as and -).

Data type

The data type of base and exponent can be any integer type (int, long int, short int). The data type of the result is also the same as the base.

Note

• If the exponent is negative, a compiler error will be generated.
• If the base is 0 and the exponent is positive, the result is 0.
• If the base is negative and the exponent is odd, the result is negative.
• If the base is negative and the exponent is even, the result is positive.
