Implement pow () function source code-CodePudding

CodePudding user response:

Pay attention to the x, y receive may lead to z overflow value of the argument, the need to consider the overflow of ~ 10 ^ 15, for example, int ~ data cannot be loaded

pay attention to the x, y receive may lead to z overflow value of the argument, the need to consider the overflow ~ 10 ^ 15, for example, the condition of type int data cannot be loaded under ~

Well well well, thank you

CodePudding user response:

Power parameter y temporary local variables can be initialized, reducing additional variables, code more compact:

 int pow (int x, int y) 
{
Int z; 
For (z=1; Y & gt; 0; - y) 
Z *=x; 
Return the z; 
}
