Well then the question is how do I know at run time how many strings are in the array of the pointers without using a MACRO and write it at Compile time ?? Jan 29, 2023 at 12:18am Mif(393) Yeah.. I know maybe is simply with C++ types but I only use C.. the title of the...
Here, we pass string array, string pointer, and string literal to the strlen function, and the function returns the length of the string. String Length Using sizeof Operator We also can use thesizeofoperator for string length (only for string literal). But, we have to subtract 1 from the...

int size = sizeof prices / sizeof prices[0];you can also use:int size = sizeof prices / sizeof *prices;as the pointer to the string points to the first item in the string.Written on Feb 6, 2020 → Get my C Handbook I wrote 19 books to help you become a better developer: ...

libC.test_string_func.argtypes = [ct.POINTER(testInStruct)] dbl_out = libC.test_string_func(sd) I have managed to make fairly complex structures work, with varying types and arrays as input. But the cause of the error passing a string in a struct eludes me. ...
Is it possible to set the maximum number of characters thatscanf()can read in using a variable? By utilizingprintf(), you can employ the asterisk symbol in this manner. #define MAXVAL 5 printf("Print at maximum MAXVAL chars: %.*s\n", MAXVAL, "myStringHere"); ...
to a pointer, and by the size of available computer memory. The string length can be stored as a separate integer, which may put an artificial limit on the length, or implicitly through a termination character, usually a character value with all bits zero such as in C programming language....
