C Fundamental Test

Example

#include <stdio.h>

int main() {
   int num = 10;
   printf("The value of num is %d\n", num);
   return 0;
}

Explanation

The above example is a simple C program that prints the value of a variable named num to the console using the printf() function. The printf() function is used to output formatted text. In this case, the formatted text is "The value of num is 10", where "10" is the value of num.

Use

A fundamental test of C knowledge usually involves asking the developer to write a basic program that demonstrates their understanding of basic C syntax. This may include understanding variable declarations, data types, input/output functions, arithmetic expressions, loops, and conditional statements.

Important Points

• C is a general-purpose programming language that was originally developed in the 1970s.
• Variables are used to store data of various types such as integers, floating-point numbers, and characters.
• The printf() function is used to display output on the console.
• The scanf() function is used to read input from the console.
• Basic programming constructs in C include loops (for, while, do-while) and conditional statements (if, else).

Summary

C is a popular programming language, known for its simplicity and efficiency. A fundamental test of C knowledge usually involves writing a basic program that demonstrates an understanding of basic C syntax, which includes variables, data types, input/output functions, arithmetic expressions, loops, and conditional statements. By understanding these fundamental concepts, developers can create powerful and efficient programs in C.
