In this tutorial we will learn writing the C program to replace first vowel of string with symbol ‘-‘ . This program will be very easy because we just have to find first character which is vowel and then replace it with ‘-‘.
You can see this program
C Program to check given character is vowel or consonant
How our this program will behave
- First we will take a string as a input from the users.
- Now to replace first vowel with ‘-‘, We will write a logic using if check to find the first occurred vowel.
- Whenever first vowel we will get, just replace this with ‘-‘.
C Program to find First occurrence of vowel and replace with ‘-‘
#include<stdio.h>
int main()
{
char str[100];
printf("=== C program to replace first vowel with '-' ===\n");
printf("Please enter a String: ");
fgets(str, 100, stdin);
for(int i=0; str[i]!='\0'; i++)
{
if(str[i]=='a'||str[i]=='e'||str[i]=='i'||str[i]=='o'||str[i]=='u'||str[i]=='A'||str[i]=='E'||str[i]=='I'||str[i]=='O'||str[i]=='U') {
str[i] = '-';
break;
}
}
printf("String after replacing first vowel with '-': %s\n", str);
return 0;
}Output
