Usesizeof()Function to Calculate Array Length in C++ In C++, thesizeof()functionallows us to determine the size of an array at compile time. Syntax: sizeof(datatype) Thesizeof()function takes a data type (e.g.,int,double,char, etc.) as its parameter and returns the size of that ...
As you know, the best way to find the length of a string is by using the strlen() function. However, in this example, we will find the length of a string manually. Calculate Length of String without Using strlen() Function #include <stdio.h> int main() { char s[] = "Programming...
sizeof(array)/sizeof(array[0]) _countof(array) These tell you thesize (capacity)of the array, i.e. how muchstorage spacethere is in the array. They donottell you anything about the currentcontentof the array! Specifically, they donottell you the "length" of the string, i.e. how ...

hello this might be noob question. how can i find the last char of an array? for example i have hello[20]; hello[0] = h hello[1] = 3 hello[2] = l hello[3] = o hello[4 and so on is blank] = i want to use the last array with value in a if else statement.
函数设计的有问题，不能返回值 void find1(char array[ ], char search, char ** pa){ int i=0;pa = NULL;while(array[i] != '\0'){ if (array[i] == search){ pa =array+ i;return;} } }
if (text.Length > 0 && start >= 0) { // Obtain the location of the first character found in the control // that matches any of the characters in the char array. int indexToText = richTextBox1.Find(text, start); // Determine whether any of the chars are found in richTextBox1....
