C programming  To declare a string, Fahim uses the following code. What will happen in the second and the third statement. Explain. (10)           char a[10]; a[0] = 98; a[1] = 97; a[2] = 'n'; a[3] = 'a'; a[4] = 'n'; a[5] = 'a'; a[6] = ‘\0’;

Backward String Design a program that prompts the user to enter a string and then displays the string contents backward. For instance, if the user enters "gravity" the program should display "“ytivarg."

C# language MORSE CODE CONVERTER Design a program that asks the user to enter a string and thenconverts that string to Morse code. Morse code is a code whereeach letter of the English alphabet, each digit, and variouspunctuation characters are represented by a series of dots anddashes. Table 8-9 shows part of the code.

String with digit.   Set hasDigit to true if the 3-character passCode contains a digit. #include <iostream>#include <string>#include <cctype>using namespace std; int main() {   bool hasDigit;   string passCode;    hasDigit = false;   cin >> passCode;      isdigit('0') == true;    if (hasDigit) {      cout << "Has a digit." << endl;   }   else {      cout << "Has no digit." << endl;   }    return 0;}

Password modifier   Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. You may assume that the string does not contain spaces and will always contain less than 50 characters. i becomes ! a becomes @ m becomes M B becomes 8 o becomes . Ex: If the input is: mypassword the output is: Myp@ssw.rdq*s LAB ACTIVITY   4.20.1: LAB: Password modifier 0 / 10     please you c programming

C++   reverse string allow the user to enter a string, display the results short code

Option #1: String Values in Reverse Order Assignment Instructions Write a Python function that will accept as input three string values from a user. The method will return to the user a concatenation of the string values in reverse order. The function is to be called from the main method. In the main method, prompt the user for the three strings.

Programming language: F95 Write a program to declare two strings of length 7 each and then form a new string by concatenation of the two strings mentioned above. Print the two strings and concatenated string in the output.

Circle Properties Write a program that prompts for and accepts the diameter of a circle as a floating point number. The program should calculate and output the area and circumference of the circle. A sample run of the program should look like this: Enter circle diameter: 2.5 The area is 4.91 and the circumference is 7.85.   Use 3.14159 as your constant for pi.     global main       ; exposes program entry point to the linkerextern printf   ; declare external functionextern scanf section .text   ; start of code segment main:   push rbp               ; preserve base pointer   mov rbp,rsp               ; copy stack pointer to base pointer    pop       rbp               ; restore base pointer   mov       rax, 0           ; exit status (0 = success)   ret section .data   ; start of initialized data segment section .bss   ; start of uninitialized data segment section .dataprompt db "Enter circle diameter: ", 0format db "The area is %0.2f and the circumference is %0.2f.", 0pi dq 3.14159…

Sum of Numbers in a String Create an application that lets the user enter a string containing series of numbers separated by commas. Here is an example of valid input: 7,9,10,2,18,6 The program should calculate and display the sum of all the numbers.
