Practical C Programming

How to do it…

1. Create a string called str to input your sentence. As usual, the last character will be a null character:

char str[255];

2. Enter a sentence of your choice:

printf("Enter a sentence: ");

3. Execute the gets function to accept the sentence with blank spaces between the words, and initialize the i variable to 0, since each character of the sentence will be accessed through i:

gets(str);i=0

4. Execute a while loop to access each letter of the sentence one by one, until the null character in the sentence is reached:

while(str[i]!='\0'){    { …    }}i++;

5. Check each letter to verify whether it is a lowercase vowel. If the accessed character is a lowercase vowel, then the value 32 is subtracted from the ASCII value of that vowel to convert ...
