Question

(c programming)

Given the function declaration and documentation below, write the function definition. Do not use the standard library function fgetc.

/// @brief Reads a character from specified file input stream.
/// @param instream A FILE* variable for an input stream to read a character from.
/// @return A character of type char from instream.
/// @note This function assumes #include <stdio.h> and a working, valid FILE* variable to an input stream.
char grabchar(FILE* instream);

Answer 1

#include <stdio.h>

char grabchar(FILE* instream);

int main()
{
FILE* instream = fopen("sample.txt", "r") ;
printf("%c",grabchar(instream));
return 0;
}

char grabchar(FILE* instream)
{
char ch;
fscanf(instream,"%c", &ch);
return ch;
}
