c语言中两个主函数怎么 C语言如何将两个函数通过主函数调用

C语言如何将两个函数通过主函数调用0

将以下两个函数通过一个主函数调用，求调用后的程序

文件的分割

#include

int main()

{

int len=0;

int len2=0;

FILE* stream;

FILE* stream1;

FILE* stream2;

char buf[50];

char buf1[50];

char buf2[50];

char text[1024];

printf("input anfile path to open:");

scanf("%s",buf);

stream=fopen(buf,"r+");

fseek(stream,0,SEEK_END);

len=ftell(stream);

printf("the file %s length is %d!\n",buf,len);

len2 = len/2;

printf("intput 2 file name: \n");

scanf("%s%s",buf1,buf2);

fseek(stream,0,SEEK_SET);

stream1=fopen(buf1,"w+");

stream2=fopen(buf2,"w+");

fread(text,len2,1,stream);

fwrite(text,len2,1,stream1);

fread(text,len-len2,1,stream);

fwrite(text,len-len2,1,stream2);

fclose(stream);

fclose(stream1);

fclose(stream2);

return 0;

}

remove(buf1);//remove the another file

return 0;
