Question

Write error message given by C compiler during program compilation, if you don't use & sign in scanf statement.​

Answer 1

Error message given by C compiler during program compilation, if '&' sign is missed in scanf statement:

Program:

#include<stdio.h>

void main()

{

char S;

printf("Enter your name:");

scanf("%s",S);

}

• In the above program, S is variable with character data type.
• printf is used to print the string given in quotes.
• scanf is used to read the character.
• %s is format specifier for string.
• When the above program is run, the compiler shows error displaying "Invalid syntax" as we did not use '&' sign before S which is supposed to point to the variable.
