Fibonacci Series with C Program

The Fibonacci Sequence is the series of numbers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

The next number is found by adding up the two numbers before it.

• The 2 is found by adding the two numbers before it (1+1)
• Similarly, the 3 is found by adding the two numbers before it (1+2),
• And the 5 is (2+3),
• and so on!

C Program to Generate Fibonacci Series:

#include <stdio.h>

int main()
{
    int n, i, num1, num2, num;
    num1 = 0;
    num2 = 1;
    printf("Enter number of terms: ");
    scanf("%d",&n);
    printf("First %d turms of Fibonacci series are:\n");
    for(i=0;i<n;i++){
        if(i<=1)
            num = i;
        else {
            num = num1 + num2;
            num1 = num2;
            num2 = num;
        }
        printf("%d ",num);
    }
    return 0;
}
