It compares the two strings and returns an integer value. If both the strings are same (equal) then this function would
return 0 otherwise it may return a negative or positive value based on the comparison.

If string1 > string2 OR string] is a substring of string2 then it would result in a negative value. If string! > string2
then it would return positive value.
If string1 == string2 then you would get O(zero) when you use this function for compare strings.

Example of strcmp:

#include
#include int main()

{ char s1[20] = "BeginnersBook";
char s2[20] = "BeginnersBook.COM";
if (stremp(sl, 52) ==0)

{

printf ("string 1 and string 2 are equal");
jelse {

printf ("string 1 and 2 are different") ;

}
return 0; } Output:

string 1 and 2 are

different

5. strrev()
உ. strrev() function reverses a given string in ( language.
#include

#include

int main()

{
char name[30] = "Hello"; — printf("String
before strrev( ) : %s\n",name); printf("String

after strrev( ) : %s",strrev(name));

return 0;
