Need help in C programming

Hello guys! This is my first post here- ok lets go to the problem. I am currently making a turn-based game and I have encountered a problem. Whenever I run the program, Player 2 always wins the game. Could you please take a look and try to fix anything if possible? Thank you very much!

#include <stdio.h>

Code:

void PreviewClasses()
{
printf("Good day!!! Lets look at each classes.\n");
printf("Swordsman is the melee class of the game and excels in close combat fights.\n");
printf("HP = 1000 MP = 500\n");
printf("Skills: Tackle\tSlash\tBlade Slash\tWhirlwind\n");
printf("\n\n");
printf("Archer prefers attacking from a distance and deal great damage with arrows.\n");
printf("HP = 800 MP = 400\n");
printf("Skils: Dual Shot\tFrost Arrow\tArrow Bomb\tCharged Shot\n");
printf("\n\n");
printf("Mage specializes in the way of magic to defeat the enemy.\n");
printf("HP = 600 MP = 1000\n");
printf("Skills: Fireball\tImpale\tDragon Slave\tFinger of Death\t\n\n");




}


int main()
{
int hp1, hp2, mp1, mp2, sa1, sa2, sa3, sa4, sb1, sb2, sb3, sb4;
char Player1, Player2, p1, p2;








PreviewClasses();


printf("Lets Begin!!!\n");


printf("Player 1 please choose your class: Swordsman = A, Archer = B, Mage = C \n");
scanf("%c", &Player1);


if(Player1 == 'A' || Player1 == 'a')
{    
hp1 = 1000;
mp1= 500;
sa1 = 90;
sa2 = 70;
sa3 = 100;
sa4 = 120;
printf("Player 1 chose SWORDSMAN.\n");
}
else if(Player1 == 'B' || Player1 == 'b')
{


hp1 = 800;
mp1 = 600;
sa1 = 90;
sa2 = 100;
sa3 = 120;
sa4 = 150;
printf("Player 1 chose ARCHER.\n");
}
else if(Player1 == 'C' || Player1 == 'c')
{
hp1 = 900;
mp1 = 800;
sa1 = 90;
sa2 = 85;
sa3 = 95;
sa4 = 100;
printf("Player1 chose MAGE.\n");
}


printf("Player 2 please choose your class: Swordsman = A, Archer = B, Mage = C \n");
scanf("%c", &Player2);
scanf("%c", &Player2);








if(Player2 == 'A' || Player2 == 'a')
{
hp2 = 1000;
mp2 = 500;
sb1 = 90;
sb2 = 70;
sb3 = 100;
sb4 = 120;
printf("Player 2 chose SWORDSMAN.\n");
}


else if(Player2 == 'B' || Player2 == 'b')
{
hp2 = 800;
mp2 = 600;
sb1 = 90;
sb2 = 100;
sb3 = 120;
sb4 = 150;
printf("Player 2 chose ARCHER.\n");
}


else if(Player2 == 'C' || Player2 == 'c')
{
hp2 = 900;
mp2 = 800;
sb1 = 90;
sb2 = 85;
sb3 = 95;
sb4 = 100;
printf("Player 2 chose MAGE.\n");
}
system("pause");


system("cls");


printf("Start Battle!\n");


do {
printf("Player 1 please choose a skill: ");
scanf("%c", &p1);
scanf("%c", &p1);




if(p1 == 'A' || p1 == 'a') 
hp2 -= sa1; 
else if(p1 == 'B' || p1 == 'b') 
hp2 -= sa2; 
else if(p1 == 'C' || p1 == 'c') 
hp2 -= sa3; 
else 
hp2 -= sa4; 
printf("\nPlayer 2's HP = %d\n", hp2);


printf("Player 2 please choose a skill: ");
scanf("%c", &p2);
scanf("%c", &p2);


if(p2 == 'A' || p2 == 'a') 
hp1 -= sb1; 
else if(p2 == 'B' || p2 == 'b') 
hp1 -= sb2; 
else if(p2 == 'C' || p2 == 'c') 
hp1 - sb3; 
else 
hp1 -= sb4; 
printf("\nPlayer 1's HP = %d\n", hp1);


} 
while(hp1 >= 0 || hp2 >= 0);


if(hp1 <= 0)
{
       printf("Player 2 wins!\n");
       }
       
       else if(hp2 <= 0)
       {
            printf("Player 1 wins!\n");
            }
system("pause");


return 0;
}

One problem is this:

Code:

while(hp1 >= 0 || hp2 >= 0);

In order for this loop to terminate hp1 < 0 AND hp2 < 0. After the loop, you check hp1 first, so player two will always win.

Instead try this:

Code:

while(hp1 >= 0 && hp2 >= 0);

Thank you very much failure67!
