C Program ONLY (Please not C++ or Java)
I need to write a program that does the following:
1.opens a text file named “Lab12input.txt” containing multiple lines of text
2.for each line, print out the condensed version of that line of text with all non-alphabetic characters removed, and all alphabetic characters turned into lower case.
Write a program that does the following:
1. opens a text file named “Lab12input.txt” containing multiple lines of text (1 or more)
2. for each line, print out “Palindrome:” and then the line of text if it IS a palindrome, and print out “Not a palindrome:” and the line of text if it is NOT a palindrome.
Thanks!
Explanation / Answer
#include <stdio.h>
#include <string.h>
int main()
{
char string1[20];
int i, length;
int flag = 0;
printf("Enter a string:");
scanf("%s", string1);
length = strlen(string1);
for(i=0;i < length ;i++)
{ if(string1[i] != string1[length-i-1]){ flag = 1; break;
}
}
if (flag) {
printf("%s is not a palindrome", string1);
}
else {
printf("%s is a palindrome", string1);
} return 0;
}
