C and C++ Compiler For Android Smartphones

In this post i'm listing some C Program compilers for Android phones or tabs. It will be very handy if you have one in your phone if you are a programming student. You don't need to have a laptop or a Personal computer with you.

C4Droid

It is a powerful offline C/C++ IDE + C/C++ compiler for Android operating System. I have been using it for 1 year. You do not need to root your phone to use this app. Its features are as listed below:

C and C++ Programs to Reverse a Number

This post includes a C program and a C++ program to reverse a given number. That is, to reverse the order of digits. If 543 is entered, it will be displayed as 345.

C Program:

#include<stdio.h>
main()
{

C and C++ Programs for String Sorting

Here i am writing programs in c and c++ languages to sort a given number of strings. Sorting is carried out based on the ASCII values of the letters in the strings. The string comparing function strcmp() is used in the program. These programs sort a given set of strings in ascending order.To change it into descending order just replace > with < in comparison line. The comparison line in the code is marked by comment.

C Program:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{

2 Different C and C++ Programs to Check Whether a Given String is Palindrome or Not

Here i am writing two different programs to check whether a given string (text) us palindrome or not. There are C and C++ programs for this.

C Programs:

(i) Using string functions:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{
char a[100],b[100];
printf("Enter the string to check if palindrome or not\n");
gets(a);
strcpy(b,a);
strrev(b);
if(strcmp(a,b)==0)
printf("\nEntered string is palindrome");
else
printf("\nEntered string is not palindrome");
getch();
} 

(ii) Comparing Character by Character

#include<string.h>
#include<stdio.h>
#include<conio.h>
void main()
{
int len,i;
char a[100];
printf("Enter the string to check whether it is palindrome or not\n");
gets(a);
len=strlen(a);
for(i=0;i<len/2;i++)
{
if(a[i]!=a[len-i-1])
break;
}

if(i==len/2)
printf("\nEntered string is palindrome");
else
printf("\nEntered string is not palindrome");
getch();
}

C++ Programs:

(i) Using String functions:

C and C++ Program to Display Pascal's Triangle

This post gives C and C++ programs to display given number of rows of pascal's triangle. Thenuser can enter the number of rows of pascal triangle to be displayed.

C Program:

#include<stdio.h>

#include<conio.h>

long factorial(int);

main()

{

int i, n, c;

printf("Enter the number of rows you wish to see in pascal triangle\n");

scanf("%d", &n);

for (i = 0; i < n; i++)

{

for (c = 0; c <= (n - i - 2); c++)

printf(" ");

for (c = 0; c <= i; c++)

printf("%ld ", factorial(i) / (factorial(c) * factorial(i - c)));

printf("\n");

}

getch();

}
