   Feb 21, 2013 · Use strlen to get the length of a null-terminated string. sizeof returns the length of the array not the string. If it's a pointer (char *s), not an array (char s[]), it won't work, since it will return the size of the pointer (usually 4 bytes on 32-bit systems).

   Apr 16, 2024 · I initialized a counter variable, length, to 0. This variable will store the length of the string. The condition of the while loop, greeting[length] != '\0', checks if the character at index length of the string is not equal to the null terminator \0. If it is not, the length variable is incremented and the loop continues and moves on to the ...

   Here, using a for loop, we have iterated over characters of the string from i = 0 to until '\0' (null character) is encountered. In each iteration, the value of i is increased by 1. When the loop ends, the length of the string will be stored in the i variable. Note: Here, the array s[] has 19 elements. The last element s[18] is the null ...

   • Then iterates through the string character by character, checking each character until it encounters the null terminator (‘\0’), which signifies the end of the string. For each character encountered, increments the length counter. Once the loop completes then returns the length which will give the length of the string.

   Oct 9, 2023 · Approach 1: Iterative (using Loop) The most traditional method of finding the length of the string is by traversing each character through the loop. Using a counter, traverse each character of the string with the help of Loop. Update the counter for every character. When the string is terminated or a null character is identified, break the loop.
