题目描述:
从文件a.txt中读取三个整数,然后把这三个整数保存到b.txt中,两整数之间一个空格。
源代码:
代码语言:javascript复制#include<stdio.h>
#include<string.h>
extern void solve();
int main(void) {
FILE *f = fopen("a.txt", "w");
fprintf(f, "%d %d %dn", 100, 123, 100);
fclose(f);
int a, b, c;
solve();
f = fopen("b.txt", "r");
int juge = 1;
fscanf(f, "%d %d %d", &a, &b, &c);
if (a != 100 || b != 123 || c != 100)
juge = 0;
if (juge) printf("YES");
else printf("NO");
return 0;
}
void solve() {
int n[3], k;
FILE *fp, *q;
fp = fopen("a.txt", "r");
for (k = 0; k < 3; k ) {
fscanf(fp, "%d", &n[k]);
}
q = fopen("b.txt", "w");
for (k = 0; k < 3; k ) {
fprintf(q, "%d ", *(n k));
}
fclose(fp);
fclose(q);
}
运行结果:
