标签:memcpy etc console 核心 for class OLE file 获取
假如分割符文件为
11 22 33
44 55 66
只获取33,66数据,代码如下,核心利用fgets读取到回车终止
#include <sys/types.h> #include <stdio.h> #include <stdbool.h> #define MAX_LEN 1024 bool ReadFile(char* filePath); int main(int argc, char** argv) { char* src = "//root//projects//ConsoleApplication3//src.txt"; ReadFile(src); getchar(); return 0; } bool ReadFile(char* filePath) { char src[MAX_LEN]; char dst[MAX_LEN]; FILE* fp = fopen(filePath, "r"); if (!fp) { printf("can‘t open file\n"); return false; } while (!feof(fp)) { memset(src, 0x00, MAX_LEN); fgets(src, MAX_LEN, fp ); int lineLength = strlen(src); int iLastPosSpace=0; for (int j = lineLength - 1; j >= 0; j--) { if (src[j] == ‘ ‘) { memset(dst, 0x00, MAX_LEN); iLastPosSpace = j; memcpy(dst, src+iLastPosSpace+1, lineLength-iLastPosSpace+1); printf(dst); break; } } } fclose(fp); return true; }
