- Write a program that reads in a line consisting of a students 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.Write a function that receives an integer. The function must return a string containing thehexadecimal representation of the integer.Write a function that finds the number of occurrences of a specified character in the string using the following header: int count(const string& s, char a) For example, count("Welcome", 'e') returns 2. Write a test program that reads a string and a character and displays the number of occurrences of the char- acter in the string.
- In C language / Please don't use (sprint) function. Write a function fact_calc that takes a string output argument and an integer input argument n and returns a string showing the calculation of n!. For example, if the value supplied for n were 6, the string returned would be 6! 5 6 3 5 3 4 3 3 3 2 3 1 5 720 Write a program that repeatedly prompts the user for an integer between 0 and 9, calls fact_calc and outputs the resulting string. If the user inputs an invalid value, the program should display an error message and re-prompt for valid input. Input of the sentinel -1 should cause the input loop to exit. Note: Don't print factorial of -1, or any number that is not between 0 and 9.

Examples: num_to_dashes(1) ➞ "-" num_to_dashes(5) ➞ "-----" num_to_dashes(3) ➞ "---"
- Write a function that returns the common characters of two strings using the following header: string commonChars(const string& s1, const string& s2) Write a test program that prompts the user to enter two strings and display their common characters. Here are some sample runs:Create a function that counts the integer's number of digits. Examples count (318) → 3 count (-92563) → 5 count (4666) -4 count (-314890) -6 count (654321)→ 6 count (638476) <- 6Using c++, Write a function that accepts a string "s" and returns the character in the string with the largest ascii value
- Write a function that returns a binary string from an octal number. The function header is as follows: string octal2Binary(const int& octalNumber) Write a test program that prompts the user to enter an octal number, uses octal- 2Binary function to parse it into an equivalent binary string and displays the binary string.In C++, write a function isVowel that returns true if a character is a vowel (whether you want to include 'y' as a vowel or not is up to you) and false otherwise. Use this function in a program that asks the user to enter a string of characters and outputs the number of vowels.in C++ language, write a program Function 1: takes as input a string, ONE character, and an integer n, and returns true if the string contains that character EXACTLY an n number of times.Function 2: takes as input a string and TWO alphabatical characters c1 and c2, and returns true if all the string characters fall in the range between the two passed characters (exclusive) (You must make sure to order the characters first if c2 < c1 ).Function 3: takes as input a string and THREE alphabatical characters c1, c2 and c3. The function reorders the characters in asecnding order, such that c1 holds the smallest character and c3 holds the largest character. The function returns true if the string characters that fall between c1 and c2 (exclusive) is less than the string characters that fall between c2 and c3 (exclusive).
