C program "palindrome"
 |
hello! I am having problems with a palindrome program. I have to input an integer between 1 and 9. and then the output has to be:
for example if I input 4:
output: 1234321
if I input 5:
output: 123454321
if 1
output: 1
for example if I input 4:
output: 1234321
if I input 5:
output: 123454321
if 1
output: 1

Ok. Consider using two for loops. One to count up to a number and one to count down. Print the looping variable.

for (count = 1; count <=n; count = count + 1)
for(count=1; count>=n; count = count - 1)
printf(“%d”, count);

Sorta. But you don't want to nest the loops. printf() after each for loop.
for ( counting up )
printf();
for ( counting down )
printf()
The second loop will be going from the upper limit to 1, remember. So limits of count=n; count>=1; count-- would make more sense.

pintf("%d",count);

printf(“%d”, count);
return 0;
}
