When storing the string values in the already initialized array, the assignment operator is not permitted, and special memory copying functions should be employed likestrcpy. #include<stdio.h>#include<stdlib.h>#include<string.h>#defineMAX_LENGTH 100#defineNUM_STRINGS 10intmain(){chararr[NUM_STRI...

In this article, we are going to discuss what an array is and how you can use them, along with examples. We will also see the concept of “strings”, which is closely related to the topic of arrays. Contents[hide] What is an array in C and why should you use them?
