C language allows arrays of three (or) more dimensions. This is a multidimensional array.The exact limit is determined by the compiler.The syntax is as follows −datatype arrayname [size1] [size2] ----- [sizen];For example, for three – dimensional array −int a[3] [3] [3];Number of elements = 3*3*3 = 27 elementsExampleFollowing is the ...

ProblemHow to write a C program to count numbers of vowels and consonants in a given string?SolutionThe logic that we will write to implement the code to find vowels and consonants is −if(str[i] == 'A' || str[i] == 'E' || str[i] == 'I' || str[i] == 'O' || str[i] == ... Read More

The structure is a collection of different datatype variables, grouped together under a single name. It is a heterogeneous collection of data items that share a common name.Features of structureIt is possible to copy the contents of all structural elements of different data types to another structure variable of its ...

Pass by value or call by value are sent as arguments.AlgorithmRefer to the algorithm for the call by value.Step 1: Enter any 2 numbers at runtime Step 2: Read those two numbers from console Step 3: Call the function swap with arguments is a call by value Step 4: Go ... Read More

Pass by reference means addresses are sent as arguments.The call by reference or pass by reference method passes the arguments to a function by the means of address to an argument. This is done into the formal parameter. Inside the function, the address is used to access an actual argument.Example#include ... Read More

Leap year is a year that consists of 366 days. For every four years, we will experience a leap year.The logic we will implement to find whether the given year by the user through the console is a leap or not −if (( year%400 == 0)|| (( year%4 == 0 ... Read More

First, open the file in write mode. Later on, enter the text until it reaches the End Of File (EOF) i.e. press ctrlZ to close the file.Again, open in reading mode. Then, read words from the file and print each word in a separate line and close the file.The logic ... Read More

The structure is a user-defined data type, which is used to store a collection of different data types of data.The structure is similar to an array. The only difference is that an array is used to store the same data types whereas, the structure is used to store different data ... Read More
