In c++ Write a function that receives a string containing a 16-bit binary integer. The function must return the string’s integer value. Write a function that receives a string containing a 32-bit hexadecimal integer. The function must return the string’s integer value. Write a function that receives an integer. The function must return a string containing the binary representation of the integer.

Using C++ Language Write a program to implement the following: • Declare two C-strings str1 and str2 of appropriate sizes. • Use strcpy() to copy the string "Hello World." into str1 • Using a suitable message, read the user input into str2. The user may enter more than one word. • Determine and store the length of both char arrays using strlen() • Check if both char arrays are the same length using the stored lengths o If they are the same length, tell the user they are the same length o If they are not the same length, tell the user the strings are different and end the program using a return statement. • Compare both strings using strcmp to check if they are the same string. o If they are the same string, inform the user of this o If they are not the same string, inform the user of this o Note that you compare only if they are of the same length, hence the return statement in the earlier step.

Match the std::string constructor on right to its function on left. Source: https://cplusplus.com/reference/string/string/string/ E string() string (const string& str) string (const char* s) string (size_t n, char c) [Choose] [Choose ] constructs a copy of str. constructs an empty string, with a length of zero characters. copies the null-terminated character sequence (C-string) pointed by s. fills the string with n consecutive copies of character c.

in C++ solve the following question in the picture :

Write a function that converts a floating-point number to a string. Provide a parameter variable for the number of digits after the decimal point. util.cpp 3 1 #include #include #include #include 6 using namespace std; 7 8 string double_to_string(double x, int digits) 9 { 10 11 } CodeCheck Reset

C++ : Write a function that inserts a given string in the middle of a second string. If the second string has an oddnumber of characters, the program first repeats the last character before inserting. Write a program to test your function.

String to integer ATOI (requires use of INT_MAX and INT_MIN): Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer (similar to C/C++'s atoi function). The algorithm for myAtoi(string s) is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of the string) is '-' or '+'. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present. Read in next the characters until the next non-digit character or the end of the input is reached. The rest of the string is ignored. Convert these digits into an integer (i.e. "123" -> 123, "0032" -> 32). If no digits were read, then the integer is 0. Change the sign as necessary (from step 2). If the integer is out of the 32-bit signed integer range [-231, 231 - 1], then clamp the integer so that it remains in the range. Specifically, integers less...

Write a C function named swap that swaps two C strings.

Write a complete function called Main() that asks the user for an input string, then creates and prints a report of how many of each character occurred in that string. For example, here is a sample run: >>> Main() Enter a string --- computer science rocks! 2 ! 1 c 4 e 3 i 1 >>> If you can put it in alphabetical order too that would be great!

3. Using c++ Write a function that accepts an integer n and returns -1 if n is less than zero and the sum of all the integers between 0 and n (inclusive) if n is greater than or equal to zero.
