In C programming language, \n and \t are escape sequences used within string literals to represent special characters:

1. \n (Newline Character):

   • \n is used to insert a newline (line break) character into a string literal or a character constant. When the string containing \n is printed or displayed, it causes the output to move to the beginning of the next line.
   • Example:
     c

      

     printf("Hello\nWorld");
     Output:
      

     Hello World
   • Here, \n causes the string "World" to be printed on a new line after "Hello".

2. \t (Tab Character):

   • \t is used to insert a horizontal tab (tabulation) character into a string literal or a character constant. When the string containing \t is printed or displayed, it causes the output to advance to the next tab stop.
   • Example:
     c

      

     printf("Name:\tJohn\tAge:\t25");
     Output:
     makefile

      

     Name: John Age: 25
   • Here, \t inserts tabs between "Name:", "John", "Age:", and "25" to align them at specific tab stops.

The C programming language is called "C" simply because it directly follows the programming language B. The precursor to C was a programming language named B, developed by Ken Thompson in 1969–1970 at Bell Labs. B itself was derived from BCPL (Basic Combined Programming Language).

When Dennis Ritchie and Brian Kernighan were developing the successor to B at Bell Labs in the early 1970s, they made significant improvements and added features that differentiated it from B. Since B came before C in the alphabet, the new language was logically named "C".

The name "C" does not officially stand for anything specific, such as "Common" or "Computing" as some might speculate. It was simply the next letter in the sequence after B.

Therefore, C is called C because it follows B in the lineage of programming languages developed at Bell Labs, with Dennis Ritchie and Brian Kernighan playing crucial roles in its creation and evolution.

1. Syntax Errors:

Syntax errors occur due to violations of the rules of the C language syntax. These errors typically prevent the program from compiling.

2. Logical Errors:

Logical errors occur when the program runs but produces incorrect results due to flawed logic in the program. These errors are often more difficult to detect and fix.

3. Runtime Errors:

Runtime errors occur while the program is running. They can be caused by various issues such as accessing invalid memory, division by zero, or incorrect function arguments.
