    int minus the amount of rand()

    So this is the begging of a text-adventure game so all the text is just story line ( and a lot have been removed but no important part ).

    But the problem is that i want "liv" ( life ) should be permanently changed after the attack.
    printf("Du har %d i liv\n", liv-rand() % 4);
    What i want to happen is that you get hit 5 times ( looped 5 times ) and hurt you a random amount between 0 -4 ( rand() % 4) ;

    liv ( life ) is hundred from the start and then
    you lose 3 health
    you lose 2 health
    you lose 1 health
    you lose 2 health
    you lose 2 health

    You now have 90 liv ( life )

    The code
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    int main()
    	char namn[20];
    	float svarhet;
    	int liv, pengar;
    	int forsta, vakt;
    	int i;
    	int menu;	 
    	printf("Välkomen till puzzlet\n");
    	printf("Vänligen skriv in din pesudonym\n"); //stava
    	scanf( "%s", namn);
    	printf("du valdet namnet %s\n\n", namn);
    	printf("välj svårighetsgrad 1 eller 2\n");
    	scanf("%d", &menu );
    	switch( menu ) {
    		case 1: liv = 100; pengar = 1000; printf("du valde den svåra"); break;
    		case 2: liv = 200; pengar = 2000; printf("Du valde det lätta spåret, mes"); break;
    		default: printf("Invalid option selected\n");
    	printf("Låt oss börja leken\n");
    	printf("# Liv %d       #\n", liv );
    	printf("# Pengar %d   #\n", pengar );
    	printf(" Liv %d Pengar %d                    \n", liv, pengar);   
    	int max = 5;
    	int d = 0;
    	int t;
    	printf("skriv 1\n"); //stava
    	scanf( "%d", &t);
    	if (t == 1 ) 
    	srand ( time(NULL) );
        	for(d = 0; d < max;d++){
      		srand ( time(NULL) );
     		printf("Du har %d i liv\n", liv-rand() % 4);
            printf("%d\n",d); // vilken loop vi är på
    	 		printf("\n\n\nDu har %d i liv\n", liv);

    Hope someone got what i mean do Englis is far away from my native language.

    Then remember: srand shall be called once and once only.
    Then you use rand() to get a random number.

    Outside of your DOS world, your header file is meaningless.

        	for(d = 0; d < max;d++){
            liv -= rand() % 4;                           
            printf("Du har %d i liv\n",liv);          // now liv after hit
            printf("%d\n",d); // vilken loop vi är på
