C/C++에서 abs(), labs() 및 llabs() 함수는 다음과 같이 변환됩니다. abs() 함수는 정수의 절대값을 반환하는 데 사용됩니다. labs() 함수는 긴 정수의 절대값을 반환하는 데 사용됩니다. llabs() 함수는 긴 정수의 절대값을 반환하는 데 사용됩니다.

int abs(int argument)

#include <cstdlib>
#include <iomanip>
#include <iostream>
using namespace std;
main() {
   int x = -145;
   int y = 145;
   cout << "Absolute value of " << x << " is: " << abs(x) << endl;
   cout << "Absolute value of " << y << " is: " << abs(y) << endl;
}

Absolute value of -145 is: 145
Absolute value of 145 is: 145

long labs(long argument)

#include <cstdlib>
#include <iomanip>
#include <iostream>
using namespace std;
main() {
   long x = -9256847L;
   long y = 9256847L;
   cout << "Absolute value of " << x << " is: " << labs(x) << endl;
   cout << "Absolute value of " << y << " is: " << labs(y) << endl;
}

Absolute value of -9256847 is: 9256847
Absolute value of 9256847 is: 9256847

long long labs(long long argument)

#include <cstdlib>
#include <iomanip>
#include <iostream>
using namespace std;
main() {
   long long x = -99887654321LL;
   long long y = 99887654321LL;
   cout << "Absolute value of " << x << " is: " << llabs(x) << endl;
   cout << "Absolute value of " << y << " is: " << llabs(y) << endl;
}

Absolute value of -99887654321 is: 99887654321
Absolute value of 99887654321 is: 99887654321
