DA = (Basic salary * 25)/100
Step 3: then calculate the HRA of basic salary using below formula
HRA= (Basic salary * 15) / 100
Step 4: then we are going to calculate Gross Salary using below formula
GS = BS + DA + HRA
Step 5: after that Provident fund is deducted using below formula
Net Salary=GS - (GS*10)/100;
Step 6: Print the value of Net Salary
Step 7: Exit
#include<stdio.h>#include<conio.h>void main(){double BS;double DA,HRA,GS,NS,PF;printf("Enter yours salary\n");scanf("%lf",&BS);DA= (BS * 25)/100;HRA= (BS * 15)/100;GS= BS+DA+HAR;PF= (GS * 10)/100;NS=GS-PF;Print("Yours Net Salary is %lf",NS);getch();}

1. What is Loop
2. Various Type of Loop
3. Example of Loop
Ans:1. for loop2. while loop3. do while loop
(1)
for loop:- for loop is used to execute statement multiple times
.
Syntax of for loop:-
for(initialization ; condition ; increment/decrement){
//body of
loop
}
Example:-
#include <stdio.h>
int main()
{
for( int i =
5; i<10;i++)
{
printf("%d\n",i);
}
return 0;
}
(2) while
loop:-The while loop is a control flow statement which is
used to execute the statement repeatedly till the condition statement is true.
Syntax for while loop:-
while (boolean condition)
{
loop
statements...
}
Example:-
#include <stdio.h>
int main()
{
int i = 5;
while
(i< 10) {
printf("%d\n",i);
i++;
}
return 0;
}
(3)
do-while:-
Do while loop is similar to while loop with a difference that do-while loop
execute the state then after that is check the condition.
Syntax for do-while loop:-
do
{
statements..
}
while (condition);
Example:-
#include <stdio.h>
int main()
{
int i = 5;
do {
printf("%d\n",i);
i++;
} while
(i< 10)
return 0;
}

1. What do you mean by an Array
2. How to declare and initialize 1-D array in C
3. What is a limitation of an array
4. Write a program to perform the addition of 3x3 matrices using an array
Array:-
An array is a non primitive linear type data structure. An array is basically a
collection of similar type of data structure which aims to bind similar data
together. It is a simple data structure where data items are accessed using
indexing.
How to declare and initialize 1-D array in C
Syntax
for declaration of array :-
1D array:- data_type[no_of_element];
2D array:- data_type[no_of_row][no_of_column];
ND array:- datatype[number]…….n times;
Iinitialization
of array :-
int arr[5] =
{1,4,6,3,8};
What is a limitation of an array
limitation
of array:-
program to perform the addition of 3x3 matrices using an array
A
program to perform the addition of 3x3 matrices using an array:-
#include<stdio.h>
#include<conio.h>
int main()
{
int matrixA[3][3],matrixB[3][3],matrixC[3][3];
int r,c,k;
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
printf("Enter
first matrix : ");
scanf("%d",
&matrixA[r][c]);
}
}
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
printf("Enter
second matrix : ");
scanf("%d",
&matrixB[r][c]);
}
}
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
matrixC[r][c]=0;
for(k=0; k<3;k++)
matrixC[r][c]
= matrixA[r][c] + matrixB[r][c];
}
}
printf("\n
New addition matrix : \n");
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
printf("
%d\t",matrixC[r][c]);
printf("\n");
}
getch();
return 0;
}
