URI Online Judge Solution | 1041 Coordinates of a Point

Here is the logic,  1041

If x!=0 and y==0 then it will be in the y asix and
If y!=0 and x==0 then it will be in the x axis

that means you have to understand if what the value is equivalent to 0 then it will be in that axis

And one thing = means assignment operator if x=y then if x=5 then y=5

and == means comparison operator if x==y then if x==4 and y==5 then x!=y so it will be false

and if x=5 and y=5 then x==y and it is true

code:

#include<cstdio>

int main()
{
    float x,y;
    while(scanf("%f %f",&x,&y)==2)
    {
        if(x==0 && y==0)
            printf("Origem\n");

        else if(y==0 && x!=0)
            printf("Eixo X\n");
        else if(x==0 && y!=0)
            printf("Eixo Y\n");
        else if(x>0 && y>0)
            printf("Q1\n");
        else if(x<0 && y>0)
            printf("Q2\n");
        else if(x<0 && y<0)
            printf("Q3\n");
        else
            printf("Q4\n");

    }

    return 0;
}

and like this can do

#include<cstdio>

int main()
{
float x,y;
while(scanf("%f %f",&x,&y)==2)
{
    if(x==0 && y==0)
        printf("Origem\n");

    else if(y==0)
        printf("Eixo X\n");
    else if(x==0)
        printf("Eixo Y\n");
    else if(x>0 && y>0)
        printf("Q1\n");
    else if(x<0 && y>0)
        printf("Q2\n");
    else if(x<0 && y<0)
        printf("Q3\n");
    else
        printf("Q4\n");

}

return 0;
}

 

 

Here in this code you have to think about the flow which normally starts from the 0 and the compiler starts punctuating the code from Zero 0.

logic flow can be start from 0 then can be happen through greater than or equal

It’s better to do in C/C++ main format

It would be a great help, if you support by sharing :)
