How do You Find Array Length in C language?

A contagious group of data items are called array. The have similar data type and name. There are several ways to find the array length in c language. One of these ways is the sizeof operator as seen below:

CPP / C++ / C Code:

int matrix[10];

printf(“%d”,sizeof(matrix) / sizeof(int));

You can also use the Blackcompe’s approach. This is one of the ways to find the array length. But there are simpler ways to do that. Through this, you will avoid determining some array base types like:

sizeof(array) / sizeof(*array)

The sizeof operator provides the storage bytes necessary to collect the object. Using this operator, you will escape from the program’s machine dependent data sizes.

Here is an example code:

#include <stdio.h>
#include <conio.h>
int array[6]= { 1, 2, 3, 4, 5, 6 };
void main() {
clrscr();
int len=sizeof(array)/sizeof(int);
printf(“Length Of Array=%d”, len);
getch();
}

The output of this code will show the length of array. The length of the provided array is 6.

It is also necessary to familiarize languages like #include, <stdio.h>, <conio.h>, clrscr(),sizeof(array)/sizeof(int) and getch() to successful translate the codes. This will help you find the array length is c language. You can check programming questions and answers and find any programming solutions you need with our help.
