C programming Interview questions and answers: TO FIND FACTORIAL OF A NUMBER USING C PROGRAM

You will find that MATLAB arrays either numeric or cell will let you do the same thing in a much faster, much more readable way.

For example, if A1 through A10 contain scalars, use: In case each Ai contains a vector or matrix, each with a different size, you want to use cell arrays, which are intended exactly for this: And be sure to use the curly braces for the subscript, not parentheses!

See the FAQ entry on cells if this is still unclear to you. Another approach is to use structures with dynamic field names instead of cell arrays.

The fields of the structure can be the variable names you want.

C++ Core Guidelines

And you can index into them with dynamic field references. You can assign anything to the field such as a scalar, an array, a string, another structure, a cell array, or whatever you want.

In this example we just assigned the integer in the index variable. Now, if you still really want to go against our advice and create variables with dynamically generated names, you need to use the eval function. So in a loop, you could use: It could be made possibly clearer to split it up into multiple lines: The fact that a variable named sin existed at runtime is irrelevant; the parsetime "decision" takes precedence.

Even in that case, you can avoid eval by using dynamic field names of a structure: Edit We present two ways of doing this: If the files that you want to process are sequentially numbered, like "file1. Also note the three different ways of building the file name - you can use your favorite way.

C Programs: String Operations Without using Library Function. No Programs; 1: C Program to count number of words digits and vowels using pointers in C Programming. Introduction. This is a brief introduction to async and await keywords and explains the basics and provides an idea how it works. Background. Asynchronous programming is essential when we develop any application because it avoids waiting in main thread on long running operations such as disk I/O, network operations database access, etc. Tags for Factorial program using function in C. program of function c language in factorial program; Program of factorial using functions; find result in c using function.

Files are in the current directory. You should save them to an array or cell array if you need to use them outside the loop, otherwise use them immediately inside the loop.

The second method is if you want to process all the files whose name matches a pattern in a directory. You can use the DIR function to return a list of all file names matching the pattern, for example all.

Warn user if it doesn't. The following folder does not exist: Or you can try a "File Exchange Pick of the Week": How do I sort file names numerically?

If you call the dir function to get file information including file nameslike this: How do I fix the error "Subscript indices must either be real positive integers or logicals.

This means that the following is permitted: Note that zero is only permitted as an index if it's not really an integer or double zero, but really "false" - a logical data type. The reason is that the indexes refer to rows and columns in the array.

So while you can have row 1 or column 3, you can't have row 3.

Table of Contents

To fix the error you must make sure that your indexes are real, positive integer numbers, or logicals. They can be scalars single numbers or vectors or arrays of many numbers.

You might take the expression for your index and make it into a single variable, like myIndexes, and then examine that in the variable editor or use code like this to figure out it's real data type and value: The official Mathworks answer to this question can be found here: Edit You cannot mix a script and function s in the same m-file.Tags for Factorial program using function in C.

Lujza Fischer author of Program to find the factorial of a given number using function declaration is from Frankfurt, Germany. GCD (Greatest Common Divisor) or HCF (Highest Common Factor) of two numbers is the largest number that divides both of them. For example GCD of 20 and 28 is 4 and GCD of 98 and 56 is A natural number greater than one has not any other divisors except 1 and itself.

In other word we can say which has only two divisors 1 and number itself. Code for Prolog program to find factorial of given number in Artificial Intelligence predicates start find_factorial(real,real) goal clearwindow, start.
