Program Plan Intro

LookupName function using Vector

Program Plan:

Include the appropriate headers into program.

Declare the “lookupName()” function.

Define the function “lookupName()” with three parameters.

The first parameter “targetName” is to identify the name in the array.

The second parameter “names” is to store names into vector.

The third parameter “numbers” is to store numbers into vector.

Declare and define the variables with its initialization.

Using “for” loop, check the “targetName” is available in array or not.

If the condition is true, assign the numbers into variable.

Assign the vector values to variable.

Return the phone number for the corresponding name.

Define the “main()” function.

Initialize the vectors for names and phone numbers.

Add the names and phone numbers to the vector using the function “push_back()”.

Using “do-while” loop, prompt the user for name.

Call the “lookupName()” function with appropriate arguments.

Using “if-else” condition, check the resultant number is in array or not.

If the condition is true, print the result.

Otherwise, print “Name not found” statement.

Get the sentinel value from user to check in “while” loop.

Can you please help me write the code in C++? It needs to be exactly wrote like the example in black. Also, if you can include a random number generator between [1,9] for the Matrixes then, that would be great. Note: Use DO-WHILE loop to verify user input for scale factor.

USE C++!! Given a string you need to print all possible strings that can be made by placing spaces (zero or one) in between them. The output should be printed in sorted increasing order of strings. You don't need to read input or print anything. Your task is to complete the function vector<string> permutation(string S) which takes the string S as input parameters and returns the sorted array of the string denoting the different permutation (DON'T ADD '(' and ')' it will be handled by the driver code only).Expected Time Complexity: O(2^n)Expected Auxiliary Space: O(1) CONSTRAINTS:1 < |S| < 10S only contains lowercase and Uppercase English letters.
