Explanation of Solution

• The #include statements at the top of the code tell the compiler to include the necessary header files. These header files contain definitions for functions and variables that are used in the code.
• The using namespace std statement tells the compiler to use the std namespace. This namespace contains many commonly used functions and variables, such as cin and cout.
• The solveMeFirst function takes two integers as input and returns their sum. The function definition starts with the keyword int, which tells the compiler that the function returns an integer value. The function name is solveMeFirst, and it takes two arguments, a and b. The body of the function is enclosed in curly braces ({}). The first line of the function body returns the sum of a and b.
• The main function is the entry point of the program. It prompts the user to enter two integers, calls the solveMeFirst function to calculate their sum, and then prints the sum to the console. The main function definition starts with the keyword int, which tells the compiler that the function returns an integer value. The function name is *main, and it takes no arguments. The body of the function is enclosed in curly braces ({}). The first line of the function body reads two integers from the user. The second line calls the solveMeFirst function to calculate the sum of the two integers. The third line prints the sum to the console.
