Ch5 Assignment -6

1. Who developed C language and when?
Ans: Dennis Ritchie in 1972 AD
2. List out any four major features of C langauge.
3. List out the major four compenents of C program.

5. Compare source file, object file and executable file
Ans: Source File: The file which contains original code of high level language is called source file. e.g. abc.c . This is the code collection written by the programmer.
Source file is translated into machine understandable form called object file. e.g. abc.obj . Object file is created by the compiler.
The linker produces an executable program located in a disk file with dot exe extension and the same name as the object file(for example, abc.obj is linked to create abc.exe).

Ch5 Assignment -9

1. Compare simple statement and compound statement.
Ans:


Simple statement:

A simple statement consists of an expression followed by a semicolon. The execution of a simple statement causes the expression to be evaluated.
Example:
b=5;
c=d+e;
printf("Enter a number");

---

Compound statement:

A compound statement consists of several individual Statements enclosed in a pair of braces { } . It provides capability for embedding Statements within other statements.
Example:
{
r=5;
area=3.14*r*r;
}
It shows a compound statement to calculate the area of the circle.
