No; the execution does.
There should be some starting point know in order to anything so C look for main Because where to start its execution(compilation). by santhosh bairam
It start with function - main()
The int main() function named main because by writing this we are trying to reduce the name conflicts from the above function defination which can be anything by the user defined function
After main()
It's called 'main' by tradition; this feature lets the linker to know, where to start the execution.
What is the main difference between compilation and interpretation? Give an example of languages of compilation and interpretation respectively.
The main function is the entry point for the application. Each program written in C or C++ will start at the first line in the main function, and cease execution once the main function returns control to the operating system (either via a return keyword in the main function, an exit(3) function call, or by "running off" the end of the main function). A program will not compile if it is missing the main function. Some variants of C++ have an alternate entry point (including those written for Microsoft Windows).
A function prototype is a declaration of a function that specifies its name, return type, and parameters without providing the actual body or implementation of the function. It serves as a way to inform the compiler about the function's existence and how it can be called. In languages like C and C++, prototypes are typically placed before the main function or in header files, allowing for proper type checking during compilation. This helps to ensure that the function is used correctly throughout the code.
The main function to use would be the SUM function. They could type it in directly or start it with the function wizard or best of all the Autosum.
Every C program must have a function, named main(), which is where the program starts execution. If there is no function main(), the computer does not know where to start running the program. The function main() must also do something; if it is just empty, some smarter compilers will note that there is nothing for the program to do, and will give this sort of error message to indicate that you forgot to tell the program what to do.
