Question

Write a C++ program that reads characters (Upper case, Lower case, and Digits ) including white spaces from the keyboard until user enters ‘#’. Then, your program should count total number of characters, uppercase letters, lowercase letters, and digits. Example of a possible input: Hello, welcome to Tempe. Today’s temperature is 117!# Approach: • First write the algorithm • Come up with a flowchart that represents the program logic. • verify your approach with sample data set • Develop the program and test it for various inputs Hint: You will need to use selection within the while loop. library has character related functions (Appendix G2,3,4 - CD). Will be discussed during the lab. Also, string data type has a method length() which gives how many characters are stored in the string.Write a program that reads characters (Upper case, Lower case, and Digits ) including white spaces from the keyboard until user enters ‘#’.

Answer 1

Below is the c++ program with detail explanation on each line

Step-by-step explanation:

// C++ program to demonstrate

// accessing of data members

#include <bits/stdc++.h>

#include <conio.h>

using namespace std;

int main() {

//Declaring variable for every type that we need to check

int totalUpperCase=0;

int totalLowerCase=0;

int totalWhiteSpaces=0;

int totalDigits=0;

//define x variable which will hold character input from user

char x;

while(x != '#'){ //execute until # character entered by user

x=getche(); //as we want from user to enter as many character as

//user wants without pressing enter key, that's why we use getche() which means

//get one character.

//isaplha method is used to check whether character is alphabet or not

if(isalpha(x)){

//isupper will check if entered character is upper case or not

if (isupper(x))

totalUpperCase++;

else

totalLowerCase++;

//isdigit method is used to check number

} else if(isdigit(x)){

totalDigits++;

} else if(x == ' '){

totalWhiteSpaces++;

}

}

//printing all the values here

cout<<"\\"<<"Total Upper Case Letters :" << totalUpperCase<<"\\";

cout<<"Total Lower Case Letters :"<<totalLowerCase<<"\\";

cout <<"Total White Spaces :"<< totalWhiteSpaces<<"\\";

cout << "Total Digits" <<totalDigits<<"\\";

// getche() at the end so that our programs wait until user presses any key

getche();

return 0;

}
