See the C FAQ, Question 1.32 Q: What is the difference between these initializations? char a[] = “string literal”; char *p = “string literal”; My program crashes if I try to assign a new value to p[i]. A: A string literal (the formal term for a double-quoted string in C source) can be used in … Read more
Try something more like this: int indexOf(const char * sequence, char ch) { const char *p = sequence; while (*p != ‘\0’) { if (*p == ch) { return p – sequence; } } return -1; } const char* findFirstOf(const char * sequence, const char *chars) { const char *p = sequence; while (*p != … Read more
Remove the address operator: bResult = ReadFile(hCom, inBuffer.GetBuffer(1), 1, &nBytesRead, NULL); Also: Don’t forget the matching call to ReleaseBuffer. And for adding that character allData += inBuffer; should be sufficient.
There are some facts about c you’re missing: There’s no string datatype. A string is just a sequence of char ending with a 0 byte. What you use here is a string literal — the compiler translates it to an array of char and automatically adds the 0 at the end. An array when passed … Read more
\u is a special code in printf; your code contains \username which is causing the error you are getting. I suspect you just have a typo there; if not, represent a backslash in printf with \\. Per @Jim Balter’s comment, you probably used \ where you meant /.
Actually % is not the modulo operand or modulo operator here because it’s included inside a string. It’s just a character chosen to separate literal text from parameters. And d is used because it performs input and output in decimal (base 10).
We, beginners, should help each other. If the function deals with strings then the second parameter of the function is redundant. A straightforward approach without using standard containers as for example std::set can look the following way #include <iostream> void missing( const char s[] ) { const char *letter = “abcdefghijklmnopqrstuvwxyz”; for ( size_t i … Read more
You are not appending characters to the array, nor are you appending pointers to the pointer array. Here are some steps you will need to perform: 1. Maintain an index or pointer to the next available location in the “sentences” array. 2. After reading the string from the file file, copy its contents to the … Read more
