**To find the absolute value of a number in C++, you can use the abs() function from the cmath library. This function returns the absolute value of the specified number.**<\/p>\n

Absolute value is the magnitude of a real number without regard to its sign. It is a common mathematical operation that is often needed in programming, including in C++. Here is how you can easily find the absolute value of a number in C++:<\/p>\n

“`cpp
\n#include
\n#include <\/p>\n

int main() {
\n int num = -5;<\/p>\n

int abs_value = abs(num);<\/p>\n

std::cout << \"The absolute value of \" << num << \" is \" << abs_value << std::endl;\n\n\n return 0;
\n}
\n“`<\/p>\n

In this example, the abs() function is used to find the absolute value of the number -5, which is 5. The abs() function works for both integer and floating-point numbers.<\/p>\n
