Invert string function reverse

Invert string function reverse: Used to invert the positions of characters in string S,
If the initial value of the original string is 123456, you can use the reverse function to put it upside down to 654321,
The procedure is as follows:
# Include <stdio. h>
# Include <string. h>
Void reverse (char s [])
{
Int C, J, I;
For (I = 0, j = strlen (S)-1; I <j; I ++, j --) // completes the inversion function, the string Terminator '/0' is not included'
{
C = s [I];
S [I] = s [J];
S [J] = C;
}
}
Main () // main function, used to test the reverse function
{
Char s [] = "123456 ";
Reverse (s); // call the inverted Function
Printf ("Inverted string: % s/n", S); // output inverted string
}


The running result is as follows; 654321
