c语言，读文件数据，并进行简单处理
static void read_file(const char * filename) { FILE * fp; char line[60]; char date [11]; float PRev_f, next_f; int prev, next; if((fp = fopen(filename, "r")) != NULL) { while(fgets(line, 60, fp) != NULL) { line[strlen(line) - 1] = '/0'; //printf("%s/n", line); sscanf(line, "%s %f %f", date, &prev_f, &next_f); prev = prev_f * 100; next = next_f * 100; printf("date:%s, prev:%d, next:%d/n", date, prev, next); //write_data(date, prev, next); } fclose(fp); } }参考文章 sscanf： http://www.cnblogs.com/lyq105/archive/2009/11/28/1612677.html fgets： http://blog.csdn.net/daiyutage/article/details/8540932
