用C语言编:有一个函数Y={X (X<1);2X-1 (1≤X<10);3X-1 (X≥10)写一个程序,输入X,输出Y

#include <stdio.h>

#include <stdlib.h>

int func( int x )

int main( int argc, char *argv[] )

{

int x, y

printf("Please input an integer : ")

scanf("%d", &x)

y = func( x )

printf("The result of call the func function %d\n", y)

return 0

}

int func( int x )

{

if( x <1)

{

return x

}

else if( x >= 10 )

{

return (3*x-1)

}

else

{

return (2*x-1)

}

}

C :

int input()

{

int x

printf("input %d",x)

scanf("%d",&x)

return x//x*x)

}

int main()

{

int y

y=input()

printf("input %d",y)

}

Pascal:

program input

var x,y :integer

readln(x)

writeln(x)

y:=x

writeln(y)

end

Basic:

dim x as integer,y as integer

read x

print x,y

end

#include <iostream.h>

int main()

{

float iX

cout<<"Please input a value: "

cin>>iX

float iY

if (iX<1){

iY = iX

}else if(iX>=1 && iX<10){

iY = 2*iX-1

}else if (iX >= 10){

iY = 3*iX

}

cout<<"y="<<iY<<endl

    return 0

}
