If a player rolls 2 dice, how do i keep track of the number of times...

You can create an array of structure to hold the info about every roll

C code :

#include <stdio.h>
// Define a structure to hold the dice rolls
struct dice_roll
{
    int dice1_roll;
    int dice2_roll;
    int total;
};

int main()
{
    int i;
    // Now we create an array of type dice_roll that will hold all the info about them
    struct dice_roll arr[3];
      
    for(i=0;i<3;i++)
    {  
        printf("\nInfo about roll %d ",i+1);
        printf("\nEnter the value on dice 1 : ");  
        scanf("%d",&arr[i].dice1_roll);  
        printf("\nEnter the value on dice 2 : ");
        scanf("%d",&arr[i].dice2_roll);
        arr[i].total = arr[i].dice1_roll + arr[i].dice2_roll;
    }
    // Now we display the results
    for(i=0;i<3;i++)
    {   printf("\nInfo about roll %d ",i+1);
        printf("\nValue on dice 1 = %d",arr[i].dice1_roll);
        printf("\nValue on dice 2 = %d",arr[i].dice2_roll);
       printf("\nTotal value on the two dice = %d ",arr[i].total);
    }
}

Output :
