In C, any function that is declared with void, for example void<\/strong> main()<\/code> can not return a value. However, functions that are declared with int<\/strong>, float<\/strong><\/code> or char<\/strong><\/code>MUST<\/strong> return a value. <\/p>\n\n\n

\n#include"stdio.h"\nint main()\n{\n\tprintf("Hacker World");\n\tprintf("Hacker World Again");\n\tprintf("Programmers World");\n\treturn 0;                     \/\/ also use getch();  \n}\n\/* dev c++ softwere me void main() support nhi krta hai aap turbo c++ me void main() bhi use kr skte hai\n #include<conio.h> aap use nhi krte hai aur getch(); use krenge to error aayega *\/\n<\/pre><\/div>\n\n\n
return 0<\/code> and getch()<\/code> are two different things in C programming:<\/p>\n\n\n\n
    \n
  1. return 0<\/code> is a statement used to indicate that a function (usually the main<\/code> function) has completed successfully and to return a value to the operating system. The value 0<\/code> is commonly used to indicate success, but other values can also be used to indicate different types of errors or status codes.<\/li>\n<\/ol>\n\n\n\n
