analyze:
First, at the beginning of the code, include the <stdio.h> header file. This header file provides input and output functions.
Then, four variables are defined: f, f1, f2 and i. f1 and f2 are the first two numbers of the Fibonacci sequence, initialized to 1. f is the number currently being calculated.
Next, use the printf function to print out the values of f1 and f2, and use the %10d format control character to ensure that the output width is 10 characters.
Then, use a for loop to iterate through each number in the sequence from 3 to 40. In the loop body, calculate the new number through f=f1+f2, update f1 to f2, and update f2 to f.
If i is divisible by 4, use printf("\n") to break the line so that the output results are aligned on the line.
Code:
#include<stdio.h>
int main()
{
long f,f1,f2;int i;
f1=1;f2=1;
printf("%10d%10d",f1,f2);
for(i=3;i<=40;i++)
{
f=f1+f2;
printf("%10d",f);
f1=f2;
f2=f;
if(i%4==0)
printf("\n");
}
}operation result:
