Starting with C, need some help

Read about the how to pass parameters to a function, like pass the value, pass the address (by pointer). Here you need use the second one.

Qt Code:

#include <stdlib.h>
#include <stdio.h>
 
void LimitesLee(int * linf, int * lsup)
{
	printf("Introduzca limite inferior y superior.\n");
	scanf("%d",linf);
	scanf("%d",lsup);
}
 
void LimitesImprime(int linf, int lsup)
{
	printf("Limites: [%d, %d]",linf,lsup);
}
 
int main()
{ 
	int linf = 0;
	int lsup = 0;
 
	LimitesLee(&linf,&lsup);
	LimitesImprime(linf,lsup);
 
	system("pause");
	return 0;
}

#include <stdlib.h>
#include <stdio.h>

void LimitesLee(int * linf, int * lsup)
{
	printf("Introduzca limite inferior y superior.\n");
	scanf("%d",linf);
	scanf("%d",lsup);
}

void LimitesImprime(int linf, int lsup)
{
	printf("Limites: [%d, %d]",linf,lsup);
}

int main()
{ 
	int linf = 0;
	int lsup = 0;
	
	LimitesLee(&linf,&lsup);
	LimitesImprime(linf,lsup);

	system("pause");
	return 0;
}
