- What are basic data types supported in the C Programming Language? Each variable in C has an associated data type. Each data type requires different amounts of memory and has some specific operations which can be performed over it.
- What are tokens in C? Tokens are identifiers or the smallest single unit in a program that is meaningful to the compiler. In C we have the following tokens
Jan 30, 2024 · C programming Exercises, Practice, Solution: C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.
- Find the largest number among the three numbers. C. #include int main() { int a = 1, b = 2, c = 3; if (a > b && a > c) printf("%d", a); else if (b > a && b > c)
- Write a Program to check whether a number is prime or not. C. #include int main() { int N = 91; int flag = 0; for (int i = 2; i <= N / 2; i++) {
- Write a C program to calculate Compound Interest. C. #include #include int main() { double principal = 2300; double rate = 7; double time = 4;
- Write a Program in C to Swap the values of two variables without using any extra variable. C. #include int main() { int x = 10; int y = 20; printf("x: %d , y: %d\n", x, y);

An ampersand & symbol must be placed before the variable name whatnumber. Placing & means whatever integer value is entered by the user is stored at the “address” of the variable name. This is a common mistake for programmers, often leading to logical errors.
Random numbers are generated in C using the rand() command. For example: anyNum = rand()will generate any integer number beginning from 0, assuming that anyNum is a variable of type integer.
Commentsare a great way to put some remarks or description in a program. It can serves as a reminder on what the program is all about, or a description on why a certain code or function was placed there in the first place. Comments begin with /* and ended by */ characters. Comments can be a single line, or can even span several lines. It can be pla...
Debugging is the process of identifying errors within a program. During program compilation, errors that are found will stop the program from executing completely. At this state, the programmer would look into the possible portions where the error occurred. Debugging ensures the removal of errors, and plays an important role in ensuring that the ex...
The && is also referred to as AND operator. When using this operator, all conditions specified must be TRUE before the next action can be performed. If you have 10 conditions and all but 1 fails to evaluate as TRUE, the entire condition statement is already evaluated as FALSE
This format is used for two things: to set the number of spaces allotted for the output number and to set the number of decimal places. The number before the decimal point is for the allotted space, in this case it would allot 10 spaces for the output number. If the number of space occupied by the output number is less than 10, addition space chara...
Program that contains logical errors tend to pass the compilation process, but the resulting output may not be the expected one. This happens when a wrong formula was inserted into the code, or a wrong sequence of commands was performed. Syntax errors, on the other hand, deal with incorrect commands that are misspelled or not recognized by the comp...
There are 3 main control structures in programming: Sequence, Selection and Repetition. Sequential control follows a top to bottom flow in executing a program, such that step 1 is first perform, followed by step 2, all the way until the last step is performed. Selection deals with conditional statements, which mean codes are executed depending on t...
The || is also known as the OR operator in C programming. When using || to evaluate logical conditions, any condition that evaluates to TRUE will render the entire condition statement as TRUE.
No. “if” command can only be used to compare numerical values and single character values. For comparing string values, there is another function called strcmp that deals specifically with strings.
Jan 3, 2024 · C Basic Interview Questions. 1. Why is C called a mid-level programming language? C has characteristics of both assembly-level i.e. low-level and higher-level languages. So as a result, C is commonly called a middle-level language. Using C, a user can write an operating system as well as create a menu-driven consumer billing system.
