在下列语句中存在错误的是

A.int a,b;scanf(“%d %f”,&a,&b);

B.int a,b;scanf(“%d %d”,a,b);

C.int a,b;scanf(“%d%d”,&a,&b);printf(“%d %d”,a,b);

D.float a,b;scanf(“%3.2f %4.2f”,&a,&b);printf(“%f %f”,a,b);

E.float a,b;scanf(“%f %f”,&a,&b);printf(“%f %f”,a,b);

F.float a,b;scanf(“%f %f”,&a,&b);printf(“a=%4.3f,b=%4.3f”,a,b);

G.int a,b;scanf(“%2d%2d”,&a,&b);printf(“a=%d,b=%d”,a,b);

H.int a,b;scanf(“%d,%d”,&a,&b);printf(“a=%2d,b=%2d”,a,b);

I:int a,b;scanf(“a=%d,b=%d”,&a,&b);printf(“a=%d,b=%d”,a,b);

正确答案:int a,b;scanf(“%d %f”,&a,&b);;int a,b;scanf(“%d %d”,a,b);;int a,b;scanf(“%d%d”,&a,&b);printf(“%d %d”,a,b);;float a,b;scanf(“%3.2f %4.2f”,&a,&b);printf(“%f %f”,a,b);
