Here is the C code for your BASIC script:
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char x[50],text[50]="This is default text";
int x1=0,amount=50;
printf("\n");
printf("Enter something if you like! <%s> ",text);
gets(x);
if (strlen(x))
strcpy(text,x);
printf("Enter a value <%d> ",amount);
scanf("%d",&x1);
if (x1 != 0)
amount=x1;
printf("\n");
printf("The value of text$ now = %s\n",text);
printf("The amount = %d\n",amount);
getch();
}
