The effect of string functions is realized by other means, such as comparing array characters, displaying string lengths, copying strings, and so on. When comparing strings, the first is to compare the length of the string, when the length of the same time at different positions one by one corresponding character comparison size. With respect to the character length is the return value return count; The count represents the subscript at a different position on the array, and the IF (a[count]== ' s) stops the loop returning a return count when a position on the array is 0. Copying a string is done by looping through each bit on the array.

int main ()
{

Char a[10] = "Hello";
Char b[] = "Hello";

void Stringcopy (char A[],char b[]);
void Stringconcat (char A[],char b[]);
int stringcmp (char A[],char b[]);
Stringcopy (A, b);
Stringconcat (A, b);
int re = stringcmp (A, b);
printf ("%d", re);
Puts (a);



}

Comparing strings

int stringcmp (char A[],char b[])
{
int i=0;
for (;; i++)
{
if (a[i]== ' &&b[i]== ')
{
return 0;
}
else if (a[i]== ' && b[i]!= ')
{
return-1;
}
else if (b[i]== ')
{
return 1;
}


if (a[i]-b[i]!=0)
{
return a[i]-b[i];
}
}
}

String length

int GetLength (char a[])
{
int count=0;
for (;;)
{
if (a[count]== ')
{
return count;
}
count++;
}
}

Copy string

void Stringcopy (char A[],char b[])
{
int i=0;
for (;; i++)
{
A[i]=b[i];
if (b[i]== ')
{
Break
}
}

}
