Compare the size of two strings str1 and str2

Write a function to compare the sizes of two strings str1 and str2. If they are equal, return 0. If str1 is greater than str2, return 1. If str1 is less than str2, return-1, do not call the character library function of the C ++/C string. Compile the strcmp function. The function is defined as intstrcmp (const char * src, const char * dst)

[Cpp]
# Include <stdio. h>
 
Int strcmp (const char * src, const char * dst)
{
Int I = 0;
While (src [I] & dst [I])
{
If (src [I]> dst [I])
Return 1;
Else
If (src [I] <dst [I])
Return-1;
Else
I ++;
}
Return 0;
}
Int main (int argc, char * argv [])
{
Char * str1 = "abc ";
Char * str2 = "abd ";
Printf ("% d \ n", strcmp (str1, str2 ));
Return 0;
}
