Write C programs named mystring.h and mystring.c, containing the headers and implementations of the following functions.
mystring.h
#include <stdio.h>
int letter_count(char *);
void lower_case(char *);
int word_count(char *);
void trim(char *);
mystring.c
#include "mystring.h"
int letter_count(char *s)
{
// your implementation
}
void lower_case(char *s) {
// your implementation
}
int word_count(char *s) {
// your implementation
}
void trim(char *s) {
// your implementation
}
Use the provided main function to test the above functions.
#include "mystring.h"
int main(int argc, char* args[]) {
setbuf(stdout, NULL);
char str[100] = " This Is a Test ";
printf("\nInput string: \"%s\"", str);
printf("\nLetter count:%d", letter_count(str));
printf("\nWord count:%d", word_count(str));
trim(str);
printf("\nAfter trimming:\"%s\"", str);
lower_case(str);
printf("\nAfter lower case:\"%s\"", str);
return 0;
}
output should look like this:
Input string: " This Is a Test "
Letter count:11
Word count:4
After trimming:"This Is a Test"
After lower case:"this is a test"
Here is the solution to above problem. I am using string.h and ctype.h for finding stringlength and checking if letter is an alphabet or converting to lowercase. Please refer to the code screenshot for indentation
HERE IS THE C CODE FOR PROGRAM
#include "mystring.h"
#include<stdio.h>
#include<string.h>
#include <ctype.h>
int letter_count(char *s)
{
//finding string length
int length= strlen(s);
int i;
int count=0;
for(i=0;i<length;++i)
{ //checking if it is alphabet
if(isalpha(s[i]))
count++; //incrementing count
}
return count;
}
void lower_case(char *s) {
// stringlength using string.h library
int length= strlen(s);
int i;
for(i=0;i<length;++i)
{
//using to toLower to convert to
lower case
s[i]=tolower(s[i]);
}
}
//counting the number of words
int word_count(char *s) {
// your implementation
int length= strlen(s);
int i;
int count=0;
for(i=0;i<length-1;++i)
{
//if counting for word if two
consequtive space are not present
if (s[i] == ' ' && s[i+1]
!= ' ')
{
count++;
}
}
return count;
}
void trim(char *s) {
// your implementation
int length= strlen(s);
char * temp = (char
*)malloc(sizeof(char)*length);
int i=0;
int j=0;
int count=0;
//removing prefix white spaces
while(s[i]==' ')
i++;
//removing unnecessary spaces in between
while(i<length-1)
{
if(!(s[i]==' '&& s[i+1]=='
') )
{
temp[j]=s[i];
j++;
}
i++;
}
temp[j]='\0';
//copying temp to original string
for(i=0;i<strlen(temp);++i)
{
s[i]=temp[i];
}
s[i]='\0';
}
int main(int argc, char* args[]) {
setbuf(stdout, NULL);
char str[100] = " This Is a Test ";
printf("\nInput string: \"%s\"", str);
printf("\nLetter count:%d", letter_count(str));
printf("\nWord count:%d", word_count(str));
trim(str);
printf("\nAfter trimming:\"%s\"", str);
lower_case(str);
printf("\nAfter lower case:\"%s\"", str);
return 0;
}

USE C programming (pls label which file is libcipher.h and libcipher.c) Q4) A shift cipher is one of the simplest encryption techniques in the field of cryptography. It is a cipher in which each letter in a plain text message is replaced by a letter some fixed number of positions up the alphabet (i.e., by right shifting the alphabetic characters in the plain text message). For example, with a right shift of 2, ’A’ is replaced by ’C’, ’B’ is...
Please write MIPS program that runs in QtSpim (ex: MipsFile.s) Write a MIPS program that will read in a base (as an integer) and a value (nonnegative integer but as an ASCII string) in that base and print out the decimal value; you must implement a function (which accepts a base and an address for a string as parameters, and returns the value) and call the function from the main program. The base will be given in decimal and will...
Programs 1. String Utilities In this exercise you will implement several utility functions involving strings. You will place all of your function prototypes in a header file named string utils.h and all of your function definitions in a source file named string utils.c. You should implement your own main test driver program to test your functions, but you need not hand it in. a. void addChar(char *str, char c, int n) - this function should add a char c at...
