LAB 3.3 – Working with String Input and Type CastingStep 1: RemovefindErrors. cppfrom the project and add thepercentage. cppprogram in yourLab3 folder to the project. Here is a copy of the source code.1 // Lab 3 percentage. cpp2 // This program will determine the percentage3 // of answers a student got correct on a test.4 // PUT YOUR NAME HERE.56 // INCLUDE THE FILE NEEDED TO DO I/O7 // INCLUDE THE FILE NEEDED TO FORMAT OUTPUT8 // INCLUDE THE FILE NEEDED TO USE STRINGS9 using namespace std;1011 int main()12 {13string name;14int numQuestions,15numCorrect;16double percentage;1718// Get student's test data19cout << "Enter student's first and last name: ";20// WRITE A STATEMENT TO READ THE WHOLE NAME INTO THE name VARIABLE.2122cout << "Number of questions on the test: ";23cin >> numQuestions;24cout << "Number of answers the student got correct: ";25cin >> numCorrect;2627// Compute and display the student's % correct28// WRITE A STATEMENT TO COMPUTE THE % AND ASSIGN THE RESULT TO percentage.2930// WRITE STATEMENTS TO DISPLAY THE STUDENT'S NAME AND THEIR TEST31// PERCENTAGE WITH ONE DECIMAL POINT.3233return 0;34 }Step 2: Replace each capitalized comment with C++ code that does what the comment asks you to do.
