1. Write a C program to print the characters of a string in reverse.
Example:
Input:
Enter a string:Test*String67!
Output:
Reverse:!76gnirtS*tseT
Template
#include <stdio.h>
/* Include any headers here */
int main() {
/* Put your declarations here */
char str[100];
printf("Enter a string:");
/* --- Start your solution here --- */
printf("Reverse:");
/* --- End of the solution --- */
Return 0;
}
2. Write a C program to count number of Alphabets, Digits and Special Characters in a
string
Example
Input:
Enter a string:uyuy$%^78iu e
Output:
Alphabets:7
Digits:2
Special Characters:6
Template
#include <stdio.h>
/* Include any headers here */
int main() {
/* Put your declarations here */
char str[100];
int alphabets = 0, digits = 0, special = 0;
printf("Enter a string:");
/* --- Start your solution here --- */
printf("Alphabets:%d\n", alphabets);
printf("Digits:%d\n", digits);
printf("Special Characters:%d\n", special);
/* --- End of the solution --- */
Return 0;
}
3. Write a C program to count the total number of words in a given string
Example
Input:
Enter a string: This is just a long test string
Output:
Total Words: 7
Template
#include <stdio.h>
/* Include any headers here */
int main() {
/* Put your declarations here */
char str[100];
int word_count = 0;
printf("Enter a string:");
/* --- Start your solution here --- */
printf("Total Words:%d\n", word_count);
/* --- End of the solution --- */
Return 0;
}
4. Write a C program to sort characters in a given string in ascending order
Example
Input:
Enter a string:trytosortthis
Output:
Sorted:hioorrsstttty
Example2 Input:
Enter a string:this is a test to sort
Output
Sorted: aehiioorssssttttt
Template
#include <stdio.h>
/* Include any headers here */
int main() {
/* Put your declarations here */
char str[100];
int word_count = 0;
printf("Enter a string:");
/* --- Start your solution here --- */
printf("Sorted:%s", str);
/* --- End of the solution --- */
Return 0;
}
5. Write a C program to concatenate two strings
Example
Input:
String1:this is a
String2:test
Output:
Result:this is atest
Template
#include <stdio.h>
/* Include any headers here */
int main() {
/* Put your declarations here */
char str1[100], str2[50];
printf("String1:");
/* -- logic to input string -- */
printf("String2:");
/* -- logic to input string -- */
/* --- Start your solution here --- */
printf("Result:%s", str1);
/* --- End of the solution --- */
Return 0;
