Given a string and we have to convert it to sentence case using C program.
So, first of all, we have to understand - what is a sentence case? A string is in a sentence case, if first character of each sentence is an uppercase character.
Example:
Input string: "hello how are you?"
Output:
Sentence case string is: "Hello how are you?"
Input string: "hello. how are you?"
Output:
Sentence case string is: "Hello. How are you?"
Program to convert string to sentence case in C
#include <stdio.h>
#include <string.h>
// function to convert string to sentence case
void StrToSentence(char * string)
{
int length=0,i=0;
length = strlen(string);
for(i=0;i<length;i++)
{
if( (i==0) && (string[i]>='a' && string[i]<='z'))
{
string[i] = string[i] - 32;
}
else if(string[i]=='.')
{
if(string[i+1] == ' ')
{
if(string[i+2]>='a' && string[i+2]<='z')
{
string[i+2] = string[i+2] - 32;
}
}
else
{
if(string[i+1]>='a' && string[i+1]<='z')
{
string[i+1] = string[i+1] - 32;
}
}
}
}
}
// main function
int main()
{
char string[50]={0};
int length=0,i=0,j=0,k=0;
printf("\nEnter the string : ");
gets(string);
// pass the string to the function
StrToSentence(string);
printf("Final string is : %s",string);
return 0;
}
Output
Run 1:
Enter the string : hello world. how are you?
Final string is : Hello world. How are you?
Run 2:
Enter the string : hello.how are you?
Final string is : Hello.How are you?
