Write a C program to generate following sequence eg when 5 is pressed the sequence should be 0 1 1 2 3 5 and if 3 is pressed 0 1 1 2 the sequence should be according to the number pressed?

Answer 1

/* the sequence printed is Fibonacci's sequence, each element is calculated as a sum of two previous elements */
#include
int main()
{
int i;
int n;
int a0=0;
int a1=1;

printf("How many elements do you want to print? ");
scanf("%d",&n);

printf("0 ");
if (n > 0)
printf("1 ");

for (i = 2; i <= n; i++)
{
printf("%d ", a0+a1);

a1 = a0 + a1;
a0 = a1 - a0;

}
return 0;

}
