以下语法正确的if语句是_____________。
A: A.if(x＞0)printf(“%f”,x)elseprintf(“%f”,-x);
B: B.if(x＞0)｛x=x+y;printf(“%f”,x);｝elseprintf(“%f”,-x);
C: C.if(x＞0)｛x=x+y;printf(“%f”,x);｝;elseprintf(“%f”,-x)
D: D.if(x＞0)｛x=x+y;printf(“%f”,x)｝elseprintf(“%f”,-x);
A: A.if(x＞0)printf(“%f”,x)elseprintf(“%f”,-x);
B: B.if(x＞0)｛x=x+y;printf(“%f”,x);｝elseprintf(“%f”,-x);
C: C.if(x＞0)｛x=x+y;printf(“%f”,x);｝;elseprintf(“%f”,-x)
D: D.if(x＞0)｛x=x+y;printf(“%f”,x)｝elseprintf(“%f”,-x);
举一反三
- 以下if语句语法正确的是 A: if(x>0)printf("%f",x)elseprintf("%f",-x); B: if(x>0){x=x+y;printf("%f",x);}elseprintf("%f",-x); C: if(x>0){x=x+y;printf("%f",x);};elseprintf("%f",-x); D: if(x>0){x=x+y;printf("%f",x)}elseprintf("%f",-x);
- 以下if语句语法正确的是_____。 A: if(x>;0){ x=x+y; printf(“%f”,x )}elseprintf("%f", -x) ; B: if (x>;0){x=x+y; printf(”%f”,x); }elseprintf(“%f”,-x) ; C: if (x>;0)printf(“%f”，x)else (x;0){ x=x+y; printf("%f",x); } ;else printf(“%f”, -x) ;
- 以下if语句语法正确的是（） A: if（x>0） printf("%f",x)elseprintf("%f",-x); B: if（x>0）{x++;printf("%f",x);}elseprintf("%f",-x); C: if（x>0）{x++;printf("%f",x);};elseprintf("%f",-x); D: if（x>0）{x++;printf("%f",x)}elseprintf("%f",-x);
