Question 2
(b) Write a program in C to generate Fibonacci series like following : 1, 1, 2, 3, 5, 8, 13 …Generate 20 such numbers.#include<stdio.h>
#include<conio.h>
main()
{
int i,a=1,b=0,sum;
clrscr();
for(i=0;i<20;i++)
{
sum = a + b;
a = b;
b = sum;
printf("%d ",sum);
}
getch();
}
Question 3
(b) Write a program to display following pattern using nested for loops.* * * * *
* * * *
* * *
* *
*
#include<stdio.h>
#include<conio.h>
main()
{
int i,j;
clrscr();
for(i=5;i>0;i--)
{
for(j=i;j>0;j--)
{
printf("* ");
}
printf("\n");
}
getch();
}
Question 4
(b) Explain how string is defined in C. Write user defined functions for the following :(i) strlen() : to find length of string.
(ii) strcat() : to concate two strings.
#include<stdio.h>
#include<conio.h>
char* strCat(char *,char *);
main()
{
char *s1,*s2,*s3;
int len;
clrscr();
s1 = "Jaydip";
s2 = "Panchal";
len = strLen(s1);
s3 = strCat(s1,s2);
printf("\nLength of String : %d",len);
printf("\nConcatation of Two String : %s",s3);
getch();
}
int strLen(char *s)
{
int i;
for(i=0;s[i] != '\0';i++);
return i;
}
char* strCat(char *s1, char *s2)
{
int i,j;
for(i=0;s1[i] != '\0';i++);
for(j=0;s2[j] != '\0';j++,i++)
s1[i] = s2[j];
return s1;
}
Question 5
(a) Write a C program to Add two 3 X 3 Matrix.#include<stdio.h>
#include<conio.h>
main()
{
int matrix1[3][3] = {{15,25,23},{45,25,35},{15,24,12}},matrix2[3][3] = {{85,36,12},{36,32,14},{78,12,74}};
int i,j;
clrscr();
printf("\n\n First Matrix : \n\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
printf("%d ",matrix1[i][j]);
}
printf("\n");
}
printf("\n\n Second Matrix : \n\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
printf("%d ",matrix2[i][j]);
}
printf("\n");
}
printf("\n\n Sum of Two Matrix : \n\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
printf("%d ",matrix1[i][j]+matrix2[i][j]);
}
printf("\n");
}
getch();
}
Question 6
(a) Write a C program to read 10 numbers from user and find Sum, Maximum and Average of them.#include<stdio.h>
#include<conio.h>
main()
{
int number[10],sum=0,maximum = 0,i;
float average;
clrscr();
for(i=1;i<=10;i++)
{
printf("Enter Number %d : ",i);
scanf("%d",&number[i]);
}
printf("\n\nSum of all Numbers : ");
for(i=1;i<=10;i++)
{
sum += number[i];
}
printf("%d",sum);
printf("\n\nAverage of all Numbers : ");
average = sum/10;
printf("%f",average);
printf("\n\nMaximum Number is : ");
for(i=1;i<=10;i++)
{
if(maximum < number[i])
maximum = number[i];
}
printf("%d",maximum);
getch();
}
