/*********************************************************/ /* Program for computing the Fibonacci number sequence */ /* using recursion. */ /*********************************************************/ #include #include int fib(int); /* function prototype */ int main() { int i,j; printf("\n Enter the number of terms: "); scanf("%d",&i); if(i < 0) { printf("\n Error - Number of terms cannot be negative\n"); exit(1); } printf("\n Fibonacci sequence for %d terms is: ",i); for( j=1; j<=i; ++j) printf(" %d",fib(j)); // function call to return jth Fibonacci term return 0; } /********************************************************/ /* Recursive function fib() */ /*******************************************************/ int fib(int val) { if(val == 1||val==2) return 1; else return(fib(val - 1) + fib(val - 2)); }
Output:
Enter the number of terms: 10 Fibonacci sequence for 10 terms is: 1 1 2 3 5 8 13 21 34 55
