首先，c中有且僅有一個主函數，所以第一步，你必須的把兩個函數改成其他名字：
#include <stdio.h>
int function1()
{
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;
}
int function2()
{
int len=0;
int len2=0;
FILE* stream;
FILE* stream1;
char buf[50];
char buf1[50];
char text[1024];
printf("input anfile path to open:");
scanf("%s",buf);
stream=fopen(buf,"r+");
fseek(stream,0,SEEK_END);
printf("intput another file name: \n");
scanf("%s",buf1);
stream1=fopen(buf1,"r+");
fseek(stream1,0,SEEK_END);
len=ftell(stream1);
fseek(stream1,0,SEEK_SET);
fread(text,len,1,stream1);
fwrite(text,len,1,stream);
fclose(stream);
fclose(stream1);
remove(buf1);//remove the another file
return 0;
}
//第二部：如果有條件的調用它們的話，加上if語句或者switch語句，基本上都是這樣，此外，你可以把function1 和function2放入一個頭文件中，然后包含這個頭文件亦行。
void main()
{
function1();
function2();
}

不知道你的具體要求是什么，如果想從主函數調用這兩個函數，把這兩個函數名改完就可以了
#include<stdio.h>
//文件的分裂
int SplitFile ()//修改的地方
{
。。。。。 }
文件的合并
#include<stdio.h>
int ConveFile()//修改的地方
{。。。
}
void main()
{
//如果是有條件的選擇這兩個函數的話，也可以加一些if語句
SplitFile（）；
ConveFile（）；
}
