No. HackerEarth is a global hub of 5M+ developers. All reserved words must be written in lowercase; otherwise the C compiler would interpret this as unidentified and invalid. To get the length of a string value, use the function strlen(). C Programming Questions and Answers has been designed with a special intention of helping students and professionals preparing for various Certification Exams and Job Interviews.This section provides a useful collection of sample Interview Questions and Multiple Choice Questions (MCQs) and their answers with appropriate explanations. In our next posts on C# programming, we’ll add more questions for experienced and bring a few quizzes for you to practice your skills. In the case of "tolower()", the code "#include " must be present at the beginning of the program. You just need to include the entire function prototype into the parameter field of the other function where it is to be used. 33) What could possibly be the problem if a valid function name such as tolower() is being reported by the C compiler as undefined? Just include in it the function prototypes that you want to use in your program, and use the #include directive followed by the name of your header file. If the number of space occupied by the output number is less than 10, addition space characters will be inserted before the actual output number. 57) What would happen to X in this expression: X += 15; (assuming the value of X is 5). It is also possible to create user defined functions for sorting, such as those based on the balloon sort and bubble sort algorithm. An algorithm provides a step by step procedure on how a solution can be derived. 32) How do you generate random numbers in C? For example, you can write printf("10%%") to have the output appear as 10% on the screen. The modulus operator outputs the remainder of a division. 41) What is || operator and how does it function in a program? Bitwise operator programming exercises and solutions in C, If else programming exercises and solutions in C, Switch case programming exercise and solutions in C, Conditional operators programming exercises and solutions in C, Loop programming exercises and solutions in C, Array programming exercises and solutions in C, String programming exercises and solutions in C, Function and recursion programming exercises and solutions in C, Pointer programming exercises and solutions in C. By creating an array of characters, you can store string values in it. After the file was opened by the fopen() function, the fseek would require three parameters to work: a file pointer to the file, the number of bytes to search, and the point of origin in the file. However, computers would not be able to understand source codes. To do this, you indicate the name of the array without the brackets. Instead, you pass to it a pointer that will point to the array first element in memory. Likewise, the statement "x --" means to decrement the value of x by 1. Compound statements are made up of two or more program statements that are executed together. This unstructured approach to coding is usually attributed to lack of experience on the part of the programmer. For example: anyNum = rand() will generate any integer number beginning from 0, assuming that anyNum is a variable of type integer. Both functions will accept a character input value from the user. Software developer, Blogger, Learner, Music Lover... Write a C program to perform input/output of all basic data types. He loves to learn new techs and write programming articles especially for beginners. Write a C program to enter length and breadth of a rectangle and find its perimeter. myName = "Robin"; You cannot use the = sign to assign values to a string variable. It is used to convert any letter to its upper case mode. We intend you to succeed in all your endeavors. However, recall that reserved words are express in lowercase, so the C compiler will not interpret this as a reserved word. Check whether two matrices are equal or not. 19) What are header files and what are its uses in C programming? C Programming Interview Questions have become a crucial part of the interview process in almost all MNC companies. 75) Is it possible to have a function as a parameter in another function? The courses... Before we learn Puppet, let's understand: What is Configuration Management? ServiceNow is a software platform which supports IT Service Management (ITSM).
