print("ABCDEF , ABC : " . strcmp("ABCDEF" , "ABC"));
print("ABC , ABCDEF : " . strcmp("ABC" , "ABCDEF"));

output:

ABCDEF , ABC : 3 
ABC , ABCDEF : -3 


strcmp("ABCDEF" , "ABC") : 
A-A = 65-65 = 0, 
B-B = 66-66 = 0, 
C-C = 67-67 = 0,
D-A = 68-65 = 3,

Then it stop at A when A-D is not 0.

ASCII value: 

A = 65 
B = 66 
C = 67 
D = 68 
E = 69 
F = 70

Is it correct how I understand strcmp()? , I just learned about this functions from internet.

  • Is it correct after strcmp("ABC" , "ABCDEF") compare C-C = 0, it return back to A(in string1) then subtract with D(of string2) ; A-D = 65-68 = -3 ? – Kugan Kumar Jul 30 '15 at 17:32

if(strcmp("Taco", "Taco") == 0) {
 //This would return true. If the two words did not match, it would return false.
}

if(strcmp("Taco", "Taco") != 0) {
 //This would return false. If the two words did not match, it would return true.
