The condition within the while statement

Question

How can I write a condition that fulfills the same condition as inside the while clause without using a <stdbool.h>

void show_path(int a[][5])
 {
int i = 0;
int j = 0;
int cost = 0;
cost = a[j][i];
printf("Path = ");
bool x = i==4&&j==3;
while (!x) 
{
    if (a[j][i + 1] < a[j + 1][i])
    {
        printf("right  ");
        i++;
                
    }

    else if (a[j][i + 1] > a[j + 1][i])
    {
        printf("down  ");
        j++;
                
    }

    cost += a[j][i];
    x = i==4&&j==3;
        
}

printf("\ncost =%d", cost);}

i tried to do it like while(!( i==4&&j==3)) but it didn't work.
