Design a Function to print the string character by character in c
Printing Characters in a String Using a Custom C Function
To design a function to print a string character by character in C, we can use the following steps:
Declare a function with the following prototype:
C Programming
void print_string_char_by_char(char *str);The function takes a pointer to a string as input and returns nothing.
Inside the function, we can use a for loop to iterate over the string and print each character:
C Programming
void print_string_char_by_char(char *str) {
int i;
for (i = 0; str[i] != '\0'; i++) {
printf("%c", str[i]);
}
}The for loop iterates over the string until it reaches the null terminator character (\0). For each character, we use the printf() function to print it to the console.
Finally, we can return from the function:
C Programming
void print_string_char_by_char(char *str) {
int i;
for (i = 0; str[i] != '\0'; i++) {
printf("%c", str[i]);
}
return;
}C program that uses the print_string_char_by_char() function:
C Programming
#include <stdio.h>
void print_string_char_by_char(char *str);
int main() {
char str[] = "Hello, world!";
print_string_char_by_char(str);
return 0;
}
void print_string_char_by_char(char *str) {
int i;
for (i = 0; str[i] != '\0'; i++) {
printf("%c", str[i]);
}
}Output:
H
e
l
l
o
,
w
o
r
l
d
