C++ 10.17 Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs Yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: Yes Ex: If the input is: 42,000 or 1995! the output is: No Hint: Use a loop and the isdigit() function (don't forget to include the cctype library). CODE PROVIDED: #include <iostream>#include <string>#include <cctype>using namespace std; string solve(string userStr) { int start; if(userStr[0]=='-' && isdigit(userStr[1])){ start=1; } else{ start=0; } for(int i=start; i<userStr.length();i++){ if(!isdigit(userStr[i])){ return "No"; } return "Yes" }}

C programming (Strings and file I/O) Write a program that asks the user for 5 names and 5 scores (0 to 100) for the test, and write the names and scores to a file (test_score.txt). Read the file to find and display the average, lowest, and highest scores. If the name the user enters is "Jacob," assign 100 points to Jacob's score, regardless of what the user enters. Input Example James 80 Peter 76 Amy 67 Jacob 94 Jenny 92 Output Example Jacob has the highest score of 100. Amy has the lowest score of 67. The average of the test is 83. // (80+76+67+100+92)/5
