abs() functionis a library function ofcmathheader, it is used to find the absolute value of the given number, it accepts a number and returns absolute value. Note:abs() functionis also declared in<stdlib.h>header file but it is compatible for integer values, in C++ 11, the enhanced ve...
The abs are used basically for int type input in C, and int, long, long long in C++. The others are used for long, and long long type data etc. Let us see the usage of these functions. The abs() Function This function is used for int type data. So this returns the absolute ...
The abs() function returns: the absolute value of num i.e. |num| the positive value if the specified number is negative abs() Prototypes The prototypes of abs() as defined in the cstdlib header file are: int abs(int num); long abs(long num); long long abs(long long num); abs()...
