The abs() function is used to compute the absolute value of an integer value. Syntax abs() function int abs(int x) Parameters abs() function Return value from abs() Absolute value of its integer operand. Example: abs() function The following example shows the usage of abs() function. #...
Prototype: int abs(int aNum); Header File: stdlib.h (C) or cstdlib (C++) Explanation: The abs function returns the absolute value of a number (makes it positive) as an integer. Example: //Program asks for user input of an integer //It will convert it to positive if it was negative...
C 库函数 int abs(int x) 返回整数 x 的绝对值。注意:abs() 函数只适用于整数,如果需要计算浮点数的绝对值,需要使用 fabs() 函数。声明下面是 abs() 函数的声明。int abs(int x)参数x -- 要计算绝对值的整数。返回值如果x 是正数,则返回 x,如果 x 是负数,则返回它的相反数,即 -x。如果 x 是 ...
The abs() function returns: the absolute value of num i.e. |num| abs() Prototypes The prototypes of abs() as defined in the cmath header file are: double abs(double num); float abs(float num); long double abs(long double num); // for integral types double abs(T num); Note:...
下面的实例演示了 abs() 函数的用法。#include <stdio.h> #include <stdlib.h> int main () { int a, b; a = abs(5); printf("a 的值 = %d\n", a); b = abs(-10); printf("b 的值 = %d\n", b); return(0); }让我们编译并运行上面的程序,这将产生以下结果:a 的值 = 5 b 的...

The abs() Function This function is used for int type data. So this returns the absolute value of the given argument. The syntax is like below. int abs(int argument) Advertisement - This is a modal window. No compatible source was found for this media. Example #include <cstdlib> #includ...
This function returns the absolute value of an integer. Example 1 In this example, we create a basic c program to demonstrate the use ofabs()function. Open Compiler #include<stdio.h>#include<stdlib.h>intmain(){intx=-2,res;printf("Original value of X is %d\n",x);// use the abs(...
