c语言错误redefinition,C语言中提示“redefinition; different basic types 错误”是怎么回事？...

改好了

主要是void printff(float score[10],float ave) 与库函数printf重复了

#include

void readdata (float score[10])

{

int i;

printf("enter 10 student's scores:\n");

for(i=0;i<10;i++)

scanf("%f",&score[i]);

return;

}

float aver(float score[10])

{

float sum;

int i;

for(sum=0,i=0;i<10;i++)

sum=sum+score[i];

return(sum/10);

}

void printff(float score[10],float ave)

{

int i;

printf("the score which are below the average:\n");

for(i=0;i<10;i++)

if(score[i]

printf("%8.2f",score[i]);

return;

}

main()

{

void readdata (float score[10]);

float aver(float score[10]);

void printff(float score[10],float ave);

float ave,score[10];

readdata(score);

ave=aver(score);

printf("average=%6.2f\n",ave);

printff(score,ave);

}
