2. Write a program, which generates 100 random integers in the range of 1 to 100. Store them in an array and then print the arrays. Write 3 versions of the program using different loop constructs. (e.g. for, while, and do while).
--------------------------------------------------------------------------------------------------------
#include <stdio.h> POSTED BY CR@SIVA
POSTED BY CR@SIVA#include <stdlib.h>
int main()
{
int n,i=1,a[100];
printf("choose the program type option:- 1=for,2=while,3=do while :");
scanf("%d",&n);
switch (n)
{
case 1:
{ printf("generate random numbers from (1-100) using 'for' loop\n");
printf("----------------------------------------------------\n");
for (i=0;i<100;i++)

a[i]=1+rand()%99;
printf("%d\t",a[i]);
}
break;
}
case 2:

printf("-------------------------------------------------------");
while(i<=100)
{
a[i]=1+rand()%99;
printf("%d\t",a[i]);
i++; }
break;
}
case 3:

3. Write a set of string manipulation functions e.g. for getting a sub-string from a given position, Copying one string to another, Reversing a string, adding one string to another
--------------------------------------------------------------------------------------------------------
PROGRAM:-
#include<stdio.h>
#include<string.h>
#include<stdlib.h> //If we use #include<stdio. h> in your c program, it will include stdio. h file into our source program which has the information for all input, output related functions.
int main()
{
char string1[25],string2[25];
int choice;
char* p;
while (1)
{
printf("the list of string manipulation operations\n");
printf("__________________________________________\n");
printf("\n1.Finding string length\n2.Finding string concatenation\n3.Compare two strings\n4.Copying two strings\n5.Reverse of string\n6.Extract the given string\n7.Exit\n");
printf("_____________________________\n");
printf("choose (1-7) from the above list:");
scanf("%d",&choice);
switch (choice)
{
case 1:
printf("enter the string1 :");
scanf("%s",string1);
printf("the length of the string is %ld\n",strlen(string1));
printf("__________________________________________\n");
break;
case 2:
printf("enter two strings :");
scanf("%s%s",string1,string2);
strcat(string1,string2);
printf("the concatenated string is =%s\n",string1);
printf("__________________________________________\n");
break;
case 3:
printf("enter two strings :");
scanf("%s%s",string1,string2);
if (strcmp(string1,string2)==0)
{ printf("the given two strings are equal");}
else
{ printf("the given two strings are not equal\n");}
printf("__________________________________________\n");
break;
case 4:
printf("enter the string :");
scanf("%s",string1);
printf("string1=%s\n",string1);
printf("after copying string1 to string2\n");
strcpy(string2,string1);
printf("string2=%s\n",string2);
printf("__________________________________________\n");
break;
case 5:
printf("enter the string");
scanf("%s",string1);
printf("before reversing string1 = %s",string1);
strrev(string1);
printf("after reversing of string is = %s",string1);
printf("___________________________________\n");
break;
case 6:
printf("Extracting substring from a given string\n");
printf("enter the string :");
scanf("%s",string1);
printf("Enter the sub string to extract :");
scanf("%s",string2);
p = strstr(string1,string2); POSTED BY CR@SIVA
POSTED BY CR@SIVA if (p)
{
printf("string found\n");
printf("First occurence of string %s in %s is %s\n",string1,string1,p);
printf("__________________________________________\n");

{ printf("string not Found\n");
printf("__________________________________________\n");}
break;
case 7:
exit(0);
}
}
return 0;

printf("\n---------------------------------------------------------\n");
printf("Minimum value of short_int data type is %d\n",SHRT_MIN);
printf("Maximum value of short_int data type is %d\n",SHRT_MAX);
printf("\n");

5. Write a program, which generates 100 random real numbers in the range of 10.0 to 20.0, and sort them in descending order.
PROGRAM :-
POSTED BY CR@SIVA #include <stdio.h>
#include <float.h>
#include <stdlib.h>
void main()
{
int i,j,temp;
float a[100];
for (i=0;i<100;i++)
