I need to translate these java codes to c. Thanks

1. public static void main( String args[] )

2. den = s.substring(start, end);

Solution

2.

void substring(char s[], char sub[], int p, int l) {
int c = 0;

while (c < l) {
sub[c] = s[p+c-1];
c++;
}
sub[c] = \'\\0\';
}

int main()
{
char string[1000], sub[1000];
int position, length, c = 0;

printf(\"Input a string\ \");
gets(string);

printf(\"Enter the position and length of substring\ \");
scanf(\"%d%d\", &position, &length);

substring(string, sub, position, length);

printf(\"Required substring is \\\"%s\\\"\ \", sub);

return 0;
}
