I need to concatenate the person's name (variable) with a text. Following logic, it would look like this
#include <stdio.h>
int main (void){
char nome[6];
printf("Ola! Insira seu nome, por fovor: \n");
scanf("%c", &nome);
printf("Seja bem vindo, \n", nome);
return 0;
}
But it's not right. I need this in the simplest way possible.
There are 3 problems in the code:
scanf() is %s (best to use a character quantity limiter you can enter) printf() is without the placeholder to accommodate the name Then it would look like this:
#include <stdio.h>
int main (void) {
char nome[6];
printf("Ola! Insira seu nome, por fovor: \n");
scanf("%5s", nome);
printf("Seja bem vindo, %s\n", nome);
return 0;
}
See working on ideone .
There are several methods for concatenating strings in C, you can use sprinf , or strcat .
The sprintf , works equal to printf , the difference is the parameter referring to the string that you will enter the value.
You can concatenate numbers and floating points using
sscanf.
strcat:
#include <stdio.h>
#include <string.h>
int main(int argc, char **argv){
char str1[50];
char str2[50];
char cat[100];
strcpy(str1,"texto da string1"); // insere o texto em str
strcpy(str2," | nova parte do texto");
bzero(cat, 100); // limpa a variavel cat
strcat(cat, str1); // concatena valores em cat
strcat(cat, str2);
puts(cat);
}
sprintf:
#include <stdio.h>
int main(int argc, char **argv){
char str1[50];
char str2[50];
char cat[100];
sprintf(str1,"Primeira parte");
sprintf(str2,"Segunda parte");
sprintf(cat,"%s - %s",str1, str2);
puts(cat);
}
