19. Write a program to generate first n number of Fibonacci series. #include<stdio.h> #include<conio.h> int main() { int n,a,b,c,i; a=0; b=1; printf("\nEnter value of n : "); scanf("%d",&n); printf("\nFibonacci series is\n"); printf("\n%d\t%d",a,b); for(i=1;i<=n-2;i++) { c=a+b; a=b; b=c; printf("\t%d",b); } getch(); return 0; } Sample output Previous Program Next Program

17. Write a C program to find factorial of a given number. #include<stdio.h> #include<conio.h> int main() { int fact=1,num,i; printf("\nenter number : "); scanf("%d",&; for(i=1;i<=num;i++) { fact=fact*i; } printf("\nFactorial of %d is %d",num,fact); getch(); return 0; } Sample output Previous Program Next Program

21. Write a C program to find the sum and average of different numbers which are accepted by user as many as user wants. #include<stdio.h> #include<conio.h> int main() { int sum=0,n,num,i; float avg; printf("\nEnter n : "); scanf("%d",&n); for(i=1;i<=n;i++) { printf("Enter number %d :",i); scanf("%d",&num); sum=sum+num; } avg=(float)sum/n; printf("\nsum is %d",sum); printf("\nAverage is %f",avg); getch(); return 0; } Sample output Previous Program Next Program
