Use a program to name multiple file strings + numeric types

Use a program to name multiple file strings + numeric types

In many cases, we create many files, and then output them by string name. So we can use img0.jpg img1.jpg img2.jpg img3.jpg.

The following are implemented in c ++ and c respectively.

C ++

# Include

 
  
# Include

  
   
# Include

   
    
Using namespace std; int main () {for (int I = 0; I <10; I ++) {strstream ss; string ii; ss <

    
     
> Ii; string a = "img" + ii + ". jpg"; cout

     

      


      
# Include

       
        
# Include

        
         
# Include

         
          
Int main () {for (int I = 0; I <10; I ++) {char str [3] = {'\ 0'}; itoa (I, str, 10); char buf [12] = "img"; char * jpg = ". jpg "; strcat (buf, str); strcat (buf, jpg); printf (" % s \ n ", buf );}}

         

        

       
Because it is an experiment, the final result is displayed, not as a file name.
