C concat strings code example
Example 1: c concatenate strings
char str[80];
strcpy(str, "these ");
strcat(str, "strings ");
strcat(str, "are ");
strcat(str, "concatenated.");
Example 2: how to combine strings in c
#include <stdio.h>
#include <string.h>
int main() {
char str[80];
strcpy(str, "these ");
strcat(str, "strings ");
strcat(str, "are ");
strcat(str, "concatenated.");
printf("%s\n", str);
}
Example 3: program to concatenate two strings in c
#include <stdio.h>
#include <string.h>
void concatenate(char *str1, char *str2)
{
int i = strlen(str1), j = 0;
while (str2[j] != '\0')
{
str1[i] = str2[j];
i++;
j++;
}
str1[i] = '\0';
}
int main()
{
char string1[20], string2[20];
gets(string1);
gets(string2);
concatenate(string1, string2);
printf("String 1 : ");
puts(string1);
return 0;
}
Example 4: c concatenate and allocate string
char* strconcat(char *str1, const char *str2)
{
char *str = NULL;
size_t len1 = 0;
size_t len2 = 0;
if (str1)
len1 = strlen(str1);
if (str2)
len2 = strlen(str2);
if (!(str = calloc(sizeof(char), (len1 + len2 + 1))))
return NULL;
if (str1)
memcpy(str, str1, len1);
if (str2)
memcpy(str + len1, str2, len2);
return (str);
}
Example 5: objective c strings concatenate
- (NSString *)strCat: (NSString *)one: (NSString *)two
{
NSString *myString;
myString = [NSString stringWithFormat:@"%@%@", one , two];
return myString;
}
