Q4. Each statement below has a blank space to fit one of the wordsin the list given below.

1) Data files are closed in C programs by using the .. libraryfunction.

2) Storage for storing a structure type variable is allocated at . time.3) . refers to the passing of a variable's address to a function without

creating any local copy in the called function.

4) When the . Statement is executed, the program skips the remainingstatements in the loop and goes back to test the loop condition.5) The operators can be used for obtaining the of a variable.6) The function sprintf() places the result in instead of an standard

output.7) The .. function is used to compare two character strings.8) . variables are the ones that are heavily used.9) The function .. indicates the end of the file condition for a

stream-oriented data file.10) To share a variable across different files, the storage class is

used.

3) An . consists of one or more constant , variables ,function calls or operations.4) If numeric or single-character information is being entered by means of scanf()function .. symbol must precede the corresponding variable name.5) is technique whereby a function calls itself.6) The logical operator == checks for . of two values.7) A statement is used to choose from multiple possibilities which may arisedue to different values of a single variables.8) The condition (o|| 1 && 1 &o) will give result as value.9) The statement puts (Strset("Test",65)); will give result as value.10) Operators & ,^, == have .. precedence.
