Convert numbers 1. Write a C/C++ code to convert a string (like "100") into a decimal number. int convert(std::string& bstr); // "00100" 2. Write a C/C++ program to take a float number and extract sign/fraction and exponent from IEEE 754 float standard void extract(float n, uint8_t& sign, uint32_t& fraction, uint32_t& exponent); 3. Write a function in C/C++ and set a specific bit to either 1 or 0 uint32_t set_bit(uint32_t n, int p, bool s); //if s == true set the bit to 1, s == false set the bit to 0, p is the position of the bit 4. Write a function to display the bit pattern for a given number (read each bit check if it is zero or one and display) void show_bits(uint32_t n)
