How to move a file in C

问题

I need to move a file from an input to a certain folder, however, 'rename' keeps crashing the entire application.

char start[50]; 
const char dest = "C:\Windows\System32\oobe\info\backgrounds\supertemp.JPG";

printf("Please enter file to move \n");
fgets(start, sizeof(start), stdin);

if (rename(start, dest) == 0){
    printf("Success \n");
}

else{
    printf("Failed %s ", GetLastError());
}

It always crashes at ' if(rename(start, dest) ==0)'.

I don't ever get as far as retrieving an error value.

Any help would be greatly appreciated! Cheers

Two problems. You have not declared dest as an array, and you need to put a double \\ in a literal string, to prevent \ being used as an escape character.

const char dest[] = "C:\\Windows\\System32\\oobe\\info\\backgrounds\\supertemp.JPG";
