Yes, but never ever do it like this in real life:
size_t mystrlen (const char *s)
{
if (s==NULL *s=='\0') return 0;
else return 1 + mystrlen (s+1);
}
C programs do not function without functions.
Functions are very important in C++, as you can't write the simplest program to print hello without using a function. Overall you can say that function are building blocks of a C++ program. Functions can also be defined by the programmer to reduce program size.
Yes,we can compile our program without header file without any error,but we can not use any predefine functions like printf,scanf.
In the C language, the continue statement can only be used within a loop (for, while, or do). Upon execution, control transfers to the beginning of the loop.
you read the book how to solve by dromy.
A loop in computer languages is a set of statements that execute repeatedly, based on some criteria.In C and C++, the three looping statements are while, do, and for...while (test-expression) statement;/* statement executes zero or more times, until test-expression is false, test first */do statement while (test-expression);/* statement executes one or more times, until test-expression is false, test last */for (init-expression, test-expression, loop-expression) statement;/* init-expression executed once, at beginning *//* statement executes zero or more times, until test-expression is false, test first *//* loop-expression evaluated at end of each iteration */Often, statement, is a set of statements, such as...while (test-expression) {... statements}
It should work without any special action.
#include <stdio.h> int main (void) { puts ("What is a 'scan statement'?!"); return 0; }
OS-dependent. For DOS use functions kbhit and getch from conio.h
It is not possible. In C, any program must have at least one function to be able to compile and execute properly: the function main()
One or more. (In other words: you cannot write a program without at least one function.)
Without know what statements you are referring to we cannot answer.
