strcmp c program code example
Example 1: strcmp c
// use: strcmp(string1, string2);
string a = "words";
string b = "words";
if (strcmp(a, b) == 0)
{
printf("a and b match");
// strcmp returns 0 if both strings match
}
else
{
printf("a and b don't match");
// strcmp returns anything else if the strings dont match
}
Example 2: c strcmp
// strCmp implementation
// string1 < string2 => return a negative integer
// string1 > string2 => return a positive integer
// string1 = string2 => return 0
int strCmp(const char* s1, const char* s2) {
while(*s1 && (*s1 == *s2)) {
s1++;
s2++;
}
return *s1 - *s2;
}
