How to get First N Characters in String in C - Step by Step Examples
How to get First N Characters in String in C ?
Answer
In C, you can use array indexing to get the first N characters from a string.
✐ Examples
1 First 5 Characters of "Hello World" String
In this example,
- We create an array of characters named
str
with a value of"Hello World\0"
to include the null terminator. - We access the first 5 characters using array indexing with
str[0]
tostr[4]
. - Finally, we print the first 5 characters.
C Program
#include <stdio.h>
int main() {
char str[] = "Hello World\0";
char first5Chars[6];
for (int i = 0; i < 5; i++) {
first5Chars[i] = str[i];
}
first5Chars[5] = '\0';
printf("First 5 characters of the string are: %s\n", first5Chars);
return 0;
}
Output
First 5 characters of the string are: Hello
2 First 3 Characters of "apple" String
In this example,
- We create an array of characters named
str
with a value of"apple\0"
to include the null terminator. - We access the first 3 characters using array indexing with
str[0]
tostr[2]
. - Finally, we print the first 3 characters.
C Program
#include <stdio.h>
int main() {
char str[] = "apple\0";
char first3Chars[4];
for (int i = 0; i < 3; i++) {
first3Chars[i] = str[i];
}
first3Chars[3] = '\0';
printf("First 3 characters of the string are: %s\n", first3Chars);
return 0;
}
Output
First 3 characters of the string are: app
