Question

若a=3,b=4,c=5,x=1.2,y=2.4,z=-3.6,u=51274,n=128765,c1=’a’,c2=’b’.想得到以下输出格式和结果,请写出程序（包括定义变量类型和设计输出）.

Answer 1

a=_3_ _b=_4_ _c=_5
x=1.200000,y=2.400000,z=-3.600000
x+y=_3.600_ _y+z=-1.20_ _z+x=-2.40
c1=ˊaˊ_or_97(ASCII)
c2=ˊbˊ_or_98(ASCII)
main()
{int a=3,b=4,c=5;
long int u=51274,n=128765;
float x=1.2,y=2.4,z=3.6;
char c1=’a’,c2=’b’;
printf("a=%2d b=%2d c=%2d\n",a,b,c);
printf("x=%f,y=%f,z=%f\n",x,y,z);
printf("x+y=%5.2f y+z=%5.2f z+x=%5.2f\n",x+y,y+z,z+x);
printf("u=%6ld n=%9ld\n",u,n);
printf("%s %s %d%s\n","c1=’a’","or",c1,"(ASCII)");
printf("%s %s %d%s\n","c2=’a’","or",c2,"(ASCII)");
}
