C using the rename variables in the program-CodePudding

Himself wrote a simple small program, I want to rename judgment conditions, but what I want is such as: variable I %==0 64, execute commands to rename, newname want to use this value (I/64 + 1), every time the point error, not clear all their self-study did kangkang which bosses solve, here are some relevant code:

 # include & lt; Iostream> 
#include  
# include & lt; IO. H> 
# include & lt; Stdio. H>

The else if cooperate goto, ah, is show, and, considering the switch statement??
Begin1 this piece, can with circular statement,,

I didn't see you rename that where is the line of code,,

Ha ha ha really is more troublesome but I actually do is one according to the position output statements of music notes, the note of the change more limitations do loop statement, and I learn the switch the class is not good nice ha ha ha so this statement is not skilled,
Then rename statement I didn't write, I just want to ask how to write, I will now, but the trouble is

 if (I %==0 64 & amp; & I> 0) 
{
/* prompt for file to rename and new name */
Cout<& lt;" Please input the name "& lt; Cin> Oldname; 
Cout<& lt;" Please enter a new name "& lt; Cin> Newname. 
Rename (oldname, newname); 
If (rename (oldname, newname)==1) 
Goto begin1; 
Else if (rename (oldname, newname)==0) 
Cout<& lt;" Rename failure "& lt; }

Although this did I want to name but need to manually enter a name, rather than what I want the "I % 64 + 1" calculated values directly into a new file name, so use this instead of the first

CodePudding user response:

Can use the STD: : string
The string filename="MC" + to_string (I % 64 + 1) + ". TXT ".
