Question

Answer 1

Answer:

Following are the code to this question:

userVal = input()#defining a variable userVal for input the value

x= 0#defining variable x that holds a value 0

for j in userVal:#defining for loop to count input value in number

   if not(j in " .,"):#defining if block that checks there is no spaces,periods,and commas in the value

       x += 1#increment the value of x by 1

print(x)#Print x variable value

Output:

Hello, My name is Alex.

17

Explanation:

In the above-given code, a variable "userVal" is defined that uses the input method for input the value from the user end, in the next line, an integer  variable "x" is defined, hold value, that is 0, in this variable, we count all values.

• In the next line, for loop is defined that counts string value in number and inside the loop an if block is defined, that uses the not method to remove spaces, periods, and commas from the value and increment the value of x by 1.
• In the last step, the print method is used, which prints the calculated value of the "x" variable.    

 

Answer 2

Answer:

Explanation:#include <iostream>

#include<string>

using namespace std;

int main()

{

  string str;

   

cout<<"Enter String \n";

 

getline(cin,str);/* getLine() function get the complete lines, however, if you are getting string without this function, you may lose date after space*/

 

  //cin>>str;

 

  int count = 0;// count the number of characeter

  for (int i = 1; i <= str.size(); i++)//go through one by one character

  {

     

   

   if ((str[i]!=32)&&(str[i]!=44)&&(str[i]!=46))//do not count  period, comma or space

{

          ++ count;//count the number of character

      }

  }

  cout << "Number of characters are  = "; //display

cout << count;// total number of character in string.

  return 0;

}
