This is a data type that contains a character (letter, number, and so on). For example, the value of a CHAR variable can be any single-digit value, e.g. B. 'A', '4' or '#'. Examples in c and c ++! charmessage [64] ="This is a string as a char array"; ...
Here is a very simple example of a C program that is vulnerable to a stack overflow: main(intargc,char*argv[]) { func(argv[1]); }voidfunc(char*v){charbuffer[10]; strcpy(buffer, v); } Thestrcpyfunction in the above example copies the command argument into the destination buffer varia...
