Question

I have this piece of code; it works when you directly write the arguments to system(), and doesn’t work if you pass the arguments to it. Any help please?

char dest[100];
char file[50];
char dir[100];

printf("Enter source path: ");
scanf("%s", dir);

printf("Enter filename: ");
scanf("%s", file);

printf("Enter destination path: ");
scanf("%s", dest);

system("move \"c:\\users\\putty.exe\" g:\\ \n" );  /* <--works        */
system("move \"%s%s\" %s", dir,file,dest);         /* <--doesn't work */

You can try this

char dest[100];
char file[50];
char dir[100];
char command[300];
printf("Enter source path: ");
scanf("%s", dir);
printf("Enter filename: ");
scanf("%s", file);
printf("Enter destination path: ");
scanf("%s", dest);
sprintf(command,"move %s%s %s", dir,file,dest);  
system(command);
