19 mar 2012 · int abs(int v) {. return v * ((v>0) - (v<0)); } This code multiplies the value of v with -1 or 1 to get abs (v). Hence, inside the parenthesis will be one of -1 or 1. If v is positive, the expression (v>0) is true and will have the value 1 while (v<0) is false (with a value 0 for false).

11 sty 2024 · In C++, the abs () function is used to obtain the absolute value of a given numeric expression. It’s like your digital tape measure – it ignores the direction and gives you the pure distance from zero. #include <cstdlib>. int main() {. int number = -10; int absoluteValue = abs(number); // absoluteValue will be 10. }
