main(){int a = 14;float b = 78.87654321;printf(“a=%d,%3d,%x\n”, a,a,a);printf(“b=%f,%lf,%5.4lf,%e\n”, b,b,b,b);}上面程序输出结果为:
A. a=14, 14,fb=78.876541,78.876541,78.8765,7.887654e+001
B. a=14, 14,eb=78.876541,78.876541,78.87654,7.887654e+001
C. a=14, 14,eb=78.876541,78.876541,78.8765,7.887654e+001
D. a=14,14,eb=78.876541,78.876541,78.8765,7.887654e+001
