When storing multiple related data, it is a good idea to use arrays. myName = "Nurujjaman". Comparative Advantages of Arrays and Vectors Because Vectors are dynamically-allocated, they offer a relatively memory-efficient way of handling lists whose size could change drastically. However if looping functions are used in the program heavily, then it might be a good idea to use arrays even for smaller number of distinct items. 442. The array type. Video Transcript. Vector is template class and is C++ only construct whereas arrays are built-in language construct and present in both C and C++. Disadvantages. If we specify or use array as intArr[10], intArr[11], intArr[200], the C compiler will not show any error, but we will get run time errors while executing the program. The answers to these questions are stored in three separate variables. Short It allows random accessing of elements i.e. Disadvantages of array in java. Array in C Language   1234 An array allows you to use loops and other techniques that are essential when dealing with large amounts of data. If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this: Individual empty character vectors within the cell array for VariableDescriptions indicate that the corresponding variable does not have a description. Write advantages and disadvantages of using pointer. Basic Structure of C Programming, Short • Global variables make a program hard to understand.
