按照你的思路大概是这样写，仅供参考，望采纳

#include<stdio.h>
#include<string.h>
#include<stdlib.h>

int main(int argc, char *argv[])
{
    FILE *f, *g;
    int a[51] = {0}, i, n, j;
    char temp[16] = {0};
    
    f = fopen("poly.in", "r");
    g = fopen("poly.out", "w");

    while(!feof(f))
    {
        fscanf(f, "%d %d",&j, &n);
        a[n] += j;
    }

    for(i = 50; i >= 0; i--)
    {
        if(a[i] > 0)
        {
            bzero(temp, sizeof(temp));
            sprintf(temp ,"%d %d ", a[i], i);
            fwrite(temp, strlen(temp), 1 ,g);
        }
    }

    fclose(f);
    fclose(g);
    return 0;
}

你自己的代码可以这个地方加个空格再试下
