List the categories of user defined function.

• 1. Function with no arguments and no return type.

• 2. Function with no arguments and a return type.

• 3. Function with arguments and no return type.

• 4. Function with arguments and with return type.

Any two string handling function.

• strcpy( str1, str2)

• strcmd()

• strcpy()

• strcmp(str1, str2)

#include<stdio.h>

#include<math.h>

int main() {

float n, ceilVal;

printf(" Enter any S-23 4M Numeric element : ");

scanf("%f", &n);

ceilVal = ceil(n);

printf("\n The Value of %.2f = %.4f ", n, ceilVal);

return 0;

}

IN ABOVE CODE WHICH MATH FUNCTION IS USE...?

• sqrt ()

• POW()

• ceil()

• strlen()

Fibonacci series sequence....?

• 0 1 2 3 4 5 6 7

• 0 1 1 2 3 5 8 13

• 2 3 4 5 6 7 8 8

• 0 1 1 2 3 3 4 8 13

State any two advantages of function.?

• 1) Big code can be diffict to read, so when divided into smaller functions, it increases readability.

  2 2) Program becomes modul.

• 1) Big code can be difficult to read, so when divided into smaller functions, it increases readability.

  2) Program becomes modular.

• 1) Big code can be difficult to read, so when divi nto smaller functions, it increases readbty.

  2) Program becomes moalr.

• 1) Big code can be difficult to re, so when divided into smler func, it increases readability. 2) Program bemes modular.

When function is called by passing values then it is _____?

• call by reference

• call by function

• call by pointer

• call by value

No copy is generated for actual variable rather address of actual variable is passed.

• call by pointer

• Call by value

• call by function

• Call by reference

Copy of actual variable is created when function is called.

• Call by reference

• call by pointer

• call by function

• Call by value

Example:-

Function call - Swap ( x,y);

• strlen()

• strcpy()

• Call by reference

• Call by value

Original (actual) parameters do not change.

• strcpy()

• strlen()

• Call by value

• ceil()
