Replace any alphabetic character with '_' in 2-character string passCode. Ex: If passCode is "9a", output is:9_Hint: Use two if statements to check each of the two characters in the string, using isalpha(). #include #include #include using namespace std; int main() { string passCode; cin >> passCode; if (isalpha(passCode.at(9a))) { passCode = false; } if (isalpha(passCode.at(9_))) {
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
#include <iostream>
#include <string>
#include <cctype>
using namespace std;
int main() {
string passCode;
cin >> passCode;
if (isalpha(passCode.at(9a))) {
passCode = false;
}
if (isalpha(passCode.at(9_))) {
passCode = true;
}
cout << passCode << endl;
return 0;
}
