What is void main in C?

The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer type data. When our program is simple, and it is not going to terminate before reaching the last line of the code, or the code is error free, then we can use the void main().

How do you declare a string?

The classic string declaration can be done as follow: char string_name[string_length] = “string”; The size of an array must be defined while declaring a string variable because it used to calculate how many characters are going to be stored inside the string variable.

What is Getch C?

getch() is a nonstandard function and is present in conio. h header file which is mostly used by MS-DOS compilers like Turbo C. It is not part of the C standard library or ISO C, nor is it defined by POSIX. Like these functions, getch() also reads a single character from the keyboard.

What is the difference between Putchar and puts?

putchar is abbreviation for PUT CHARACTER whereas puts is abbreviation for PUT STRING. As the name specifies putchar is used for printing a single character on console or standard output whereas puts prints a string with an additional newline character at the end.

What will be the output of the statement putchar getchar ()) be?

arrow_back putchar(getchar()) Even if we try to give the input as ‘a b’ the output will be only ‘a’, cause the 2nd getchar() will take ‘\t’ as input. But if we give ‘ab’ as input, then the 2nd getchar() will consider ‘b’ as it’s input, so the o/p will be ‘ab’.

What is the value of EOF?

EOF instead is a negative integer constant that indicates the end of a stream; often it’s -1, but the standard doesn’t say anything about its actual value. C & C++ differ in the type of NULL and ‘\0’ : in C++ ‘\0’ is a char , while in C it’s an int ; this because in C all character literals are considered int s.

What is the use of Getchar?

getchar is a function in C programming language that reads a single character from the standard input stream stdin, regardless of what it is, and returns it to the program. It is specified in ANSI-C and is the most basic input function in C. It is included in the stdio. h header file.
