Call a function within the function where the wrong ah, how to change? Bosses can be solved?-CodePudding

Double vcolumn (double h) 
{
Return scircle (double r) * h; 
}

Scircle vcolumn function call function, need to pass parameters, such as scircle you (h)

CodePudding user response:

Double vcolumn (double h)
{
Return scircle (double r) * h;//scircle calls to pass arguments.
}

CodePudding user response:

Double vcolumn (double h), lack of the parameters of r. modified as follows:

 double scircle (double r) 
{
Return r * r * 3.14; 
} 

Double vcolumn (double h, double r) 
{
Return scircle (r) * h; 
} 

Int main (int arg c, char * argv []) 
{
Double r1, h1; 
Cin> R1 & gt;> H1. 
Coutreturn 0; 
}

CodePudding user response:

When call don't need to write type return scircle (r) * h;
