scanf("%d %c",&size,&chara); 有效,但单独的用于字符输入的 scanf 不起作用。我在代码中显示这些。这是为什么?
void squareCustomFill(int size, char chara);
int main(void) {
int size,i,k;
char chara;
printf("Enter size of square: "); //This works
scanf("%d %c",&size,&chara);
//printf("Enter fill character: "); BUT WHY DOES NOT THIS WORK??
//scanf("%c",&chara);
squareCustomFill(size,chara);
return 0;
}
void squareCustomFill(int size, char chara){
int i,k;
for (k=1;k<=size;k++){
for(i=1;i<=size;i++)
printf("%c",chara);
printf("\n");
}
}
