c语言 编程斐波那契数列前40项（要求每行输出4项）

Sure, here's the code for generating the first 40 terms of the Fibonacci sequence using C language:

#include <stdio.h>

int main() {
    int n, first = 0, second = 1, next;
    
    printf("The first 40 terms of the Fibonacci sequence are:\n");
    
    for(n = 0; n < 40; n++) {
        if(n % 4 == 0 && n > 0)
            printf("\n"); // start a new line every 4 terms
        
        if(n <= 1)
            next = n;
        else {
            next = first + second;
            first = second;
            second = next;
        }
        
        printf("%d\t", next); // output the next term
    }
    
    return 0;
}

I hope that helps! Let me know if you have any other questions.
