This demonstrates how these functions work with different stream types, not just files. Counting Characters in a FileHere's a practical example counting characters in a file using fgetc. count_chars.c #include <stdio.h> int main() { FILE *fp = fopen("document.txt", "r"); if (fp ==...
In C, strings are represented as arrays of characters terminated by a Null character. The Null Character in C at the end of the string ensures that functions and libraries designed to work with C strings can correctly identify the string’s length and avoid buffer overflows. For instance, th...
