C Programming Fundamentals

In year 1972 at the Bell laboratories, Dennis Ritchie has developed the C language. He developed it after developing the Basic combined programming language in 1960. C language is general purpose programming language.

In C language,  program should be written in lower case. If we use upper case, then it will show error or it'll not be run.

 It is a computer program that translates the entire user written program (known as source program) into machine language ( known as object program) at once. It's so fast so it used convert C programs into machine language.

C language has been designed & developed by Dennis M. Ritchie at bell laboratories in 1972. It is an offspring of the “ Basic combined programming language” called 'B' developed in 1960 at Cambridge university.

This symbol represents Null string. Null string is also known as empty string.

This statement is totally true. It is right that opening braces indicate begins and closing braces indicate ends of the function.

In this option, first of all click on start then program then we'll get MS-DOS option. After that, it will show the black screen. This is the right option.

This is the right option. Conio stands for Console Input Output.

This is correct. Stdio stands for Standard Input Output.

This combination of shortcut key is correct because this is used to see the output of program in C language.

The compile directives such as define & include are special instructions to the compiler to compile the program. They do not end with (;). 

This symbol is compiler directive, which must appear in the first column of the line.

 This symbol is used when any comment insert in the program. The comment is written anywhere in the program. There is a no effect of comment in the output of the program. If we will insert comment without these symbols, then it will effect the program's output.

 This is correct because in C language, Scanf function means input function.

 This is correct option because in C language, Printf function means output function.

This is correct option, because this escape character means back space.

 This combination of shortcut keys is used to compile the program.

In C language, the group of characters, digits and symbols are enclosed within quotation marks called as strings. The string is always declared as character array. In other words, character array is also a string. A string is a sequence of characters. For e.g. “Hello”, “432”, etc.

In this 'size' means how many characters can be hold in string. For example to define a string name of 10 character we can write char name[10]; hence, this option is correct.

This header file is not used in C language. This is used in C++ language because of its additional features. 

It stands for formula translation. It is developed for mathematical and scientific problems. This language is used for scientific and engineering applications where more calculation power is needed than storage and retrieve facilities.
