文件中加入字符串的相关代码操作

#include  
#include
#include 
void Fun(char *fname,char st[],int number)
{ 
        FILE *myf;
		int i;
		if(number==0)
		{
        myf=fopen(fname,"w");	
		}
		else
		{
			myf=fopen(fname,"a");
		}
        if (myf == NULL)
        {
            printf("cannot open the file.\n");
            exit(0);
        }
       for(i=0;i

*//转载相关代码说明
函数原型：int fputc(int c,FILE stream);
作用：将字符c写入stream文件中

#include 
#include 
int main(int argc,char *argv[])
{
	FILE *fp;
	char ch;
	if( argc != 2 )
	{
		printf("Usage:%s filename\n\a",argv[0]);
		exit(1);
	}
	if( (fp=fopen(argv[1],"wt+")) == NULL )
	{
		printf("File %s open failed!\n\a",argv[1]);
		exit(1);
	}
	printf("Input a string:");
	ch = getchar();
	while( ch != '\n')
	{
		fputc(ch,fp);
		ch = getchar();
	}
	printf("\n");
	return 0;
}
