2- for loop to find the index of substring cs'in input string?
Step by step
Solved in 2 steps with 1 images
- Given string stringVal on one line, integer idxStart on a second line, and integer choiceLen on a third line, replace choiceLen characters with "1234", starting at index idxStart. Ex: If the input is: Fuzzy bear 3 4 then the output is: Fuz1234ear Note: Using a pre-defined string function, the solution can be just one line of code. #include <iostream>#include <string>using namespace std; int main() { string stringVal; int idxStart; int choiceLen; getline(cin, stringVal); cin >> idxStart; cin >> choiceLen; /* Your code goes here */ cout << stringVal << endl; return 0;}Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number, and all the characters in the password are replaced by x. (The Social Security number is in the form 000- 00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element.Implement the following function which accepts a string as parameter and reverses it, without using any function from the string library. void strReverse(char *str)
- In c++ Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, th backwards End each loop with a newline. Ex If courseGrades (7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint Use two for loops. Second loop starts with i=NUM VALS-1. (Notes) Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades(4) See 'How to Use zyBooks Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message 32344345730rity? 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13 14 const int NUM VALS-4; int courseGrades [NUM VALS]; int i; for (i = 0; i > courseGrades[1]; } y Your solution goes here YMatch the std::string constructor on right to its function on left.

[Choose ]Can you write a new code in C language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file.

- In Python Use the Design Recipe to write a function weave, which consumes two strings of the same length. Your function should return a string with the two arguments interleaved together, i.e., the first character of the first string followed by the first character of the second string, followed by the second character of the first string, etc.Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1 below. Expression Effect strVar.at(index) Returns the element at the position specified by index strVar[index] Returns the element at the position specified by index strVar.append(n, ch) Appends n copies of ch to strVar, where ch is a char variable or a char constant strVar.append(str) Appends str to strVar strVar.clear() Deletes all the characters in strVar strVar.compare(str) Returns 1 if strVar > str returns 0 if strVar == str; returns −1 if strVar < str…public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments.
