### code of Game of Chance

﻿ A Game of Chance One of the most popular games o in casinos and back alleys triangular  games of chance is a dice game known as “craps,”  It is played in hack alleys throughout the world.  Following are rules of the Game: roll two dice. Each die has six faces. These faces contain one, two, three, four, five, and six spots.  the dice  to rest, the sum of the spots on the two upward faces is calculate. If sum is 7 or 11 on the first throw, the player wins.  If the sum is two, three, or twelve on the first throw Called "craps"),  the player loses (mean the "house" wins).  If the sum is four, five, six, eighth, nine, or ten on the first throw, then that sum becomes the player's "point.”  To win, you must continue rolling the dice until you make your points. The player loses by rolling a 7 before making the point.  Code of the game:  #include<stdio.h>  #include<stdlib.h>   #include<time.h>  /*contains prototype for function time */ enum Sta

### convert lower to upper case string conversion:  Here is the code of convert lower case string to upper case in the c programming language. The concept of ASCII involves in the conversion of string.   code: #include<stdio.h> #define size 100   void convet1st2Capital(char str[]); int main(void){ char str[size]; printf("Enter the string to capitalize initials:\n"); gets(str); convet1st2Capital(str); } void convet1st2Capital(char str[]){ int s = 0; while (!(str[s] == '\0')){ if (str[s] >= 'a' && str[s] <= 'z'){ str[s] -= 32; }   s++; } printf("%s", str); } Output: In this example,declare the global variable for size of character array and function to convert the lower case string to upper case string . In the function, the loop is used to check the lower case character and convert into the upper by subtracting the 32 in the character ASCII.In the last,display the string .
