我不知道你是干什么的，要是一个计算机从业者或是计算机学习爱好者的话
连这个你都不会就干点别的吧你不适合计算机
#include <stdio.h>
int main()
{
FILE* pInput = fopen( "input.txt", "r" );
if( NULL == pInput )
{
printf( "open inputfile Error!" );
return -1;
}
FILE* pOutput = fopen( "output.txt", "w" );
if( NULL == pOutput )
{
fclose( pInput );
printf( "open outputfile Error!" );
return -1;
}
while( !feof( pInput ) )
{
int iNum1 = 0;
int iNum2 = 0;
fscanf( pInput, "%d %d", &iNum1, &iNum2 );
fprintf( pOutput, "%d\n\n", iNum1 + iNum2 );
}
fclose( pOutput );
fclose( pInput );
return 0;
