c++ isalpha code example
Example 1: check if character in string is alphabet c++
int main() {
char val1 = 's';
char val2 = '8';
if(isalpha(val1))
printf("The character is an alphabet\n");

Example 2: c++ isalphanum
string test = "Ab4 :";
std::isalnum(test[0]); //true
std::isalnum(test[1]); //true
std::isalnum(test[2]); //true
std::isalnum(test[3]); //false
std::isalnum(test[4]); //false
Example 3: isalpha c++
char test='a';
cout<<isalpha(test);
