In your first example, char bacon[ 6 ], that code declares an array that will hold up to six characters; however, if you want to use strlen() or any of the functions that work on "C" strings (null-terminated character arrays), it should hold at most five characters and a null byte...

ok, so i guess, there's no functions that included the null-terminated character There is no way for a pointer to know whether it points to one object or element in an array. Naturally, it can't have the info about lenght of array. ...
If you want to determine the "length" of a string, not counting the final NULL character, use strlen() function: https://www.cplusplus.com/reference/cstring/strlen/ Warning: When using strlen() there must be a terminating NULL character in the string/array !!! BTW: sizeof() and _count...
However, if A is a string scalar, size returns [1 1] because it is a single element of a string array. For example, compare the output of size for a character vector and string: szchar = size('mytext') szchar = 1 6 szstr = size("mytext") szstr = 1 1 To find the number ...
在C语言中,`sizeof`是一个操作符,用于计算数据类型或变量所占用的内存大小(以字节为单位)。例如: ```c int a; size_t size_of_a = sizeof(a); // s...

32, where the character array is declared with size of the number I need to import to string format. When the program reaches a certain point I get an overflow I am assuming due to the fact that there are too many digits in the number to be stored in the character array. Suggestions?

Whendimis specified, the number of output arguments must equal the number of queried dimensions. If you specify more thanndims(A)output arguments, then the extra trailing arguments are returned as1. Data Types:double Tips To determine if an array is empty, a scalar, or a matrix, use the ...
