A. Write a complete, working C++ program called that does the following: Extract the numeric value from a string (See Sample Output). Assume that the numeric value is always an integer, never a floating-point number.

• Declare a string variable to read a string from the user.

• Using suitable prompt, read a string from the user. The string can have multiple words,

  each word separated by a single space.

• Declare an integer variable named value to store numeric value extracted from the string

  and initialize it to 0.

• Declare an integer variable named index to compute the numeric value.

• In a loop of your choice:

o Parse the string one character at a time. In this loop, you need parse the string in order of starting from the last character to the first character i.e. test the final character first.

o Check if the character is a digit. o Using variable index as index and 10 as base, compute power. o Multiply the computed power with the numeric value of extracted digit.

HINT: The ASCII value of character 0 is 48, while the numeric value is 0.o Accumulate the product of the above multiplication in the variable value. o Increment index by 1 after processing each digit.

• Display the computed value using with a suitable message.

• Increment the computed value by 100 and display the incremented value with a suitable

  message.

• Due to time constraints, no comments are required in this code.
