I have this activity, exercise, where is to display the largest number, but is giving the error:
"incompatible type for argument 1 of 'printf' "
On the command line "printf (valor2);".
Code:
#include <stdio.h>
main()
{
double valor1, valor2;
scanf ( "%lf", &valor1);
scanf ( "%lf", &valor2);
if ( valor1>valor2)
{
print ( valor1);
}
else if (valor1< valor2)
{
printf (valor2)
}
}

There are several errors in your code, I believe because you are a beginner! I recommend reading about printf and scanf functions
Read this answer too Difference between %i and %d
Your functional code looks like this:
#include <stdio.h>
int main()
{
double valor1, valor2;
scanf ( "%lf", &valor1);
scanf ( "%lf", &valor2);
if ( valor1>valor2){
printf("%f", valor1);
}
else if (valor1 < valor2){
printf("%f", valor2);
}
}
Just a small hint, as you will compare only 2 variables, could do with the structure if-else instead of if-elseif:
#include <stdio.h>
int main()
{
double valor1, valor2;
scanf ( "%lf", &valor1);
scanf ( "%lf", &valor2);
if ( valor1>valor2){
printf("%f", valor1);
}
else {
printf("%f", valor2);
}
}
As recalled by the Cat, there is still a third possibility using ternary operator, or conditional operator:
Read on this question: When should I use the "?" operator in C?
#include <stdio.h>
int main()
{
double valor1, valor2, resultado;
scanf ( "%lf", &valor1);
scanf ( "%lf", &valor2);
resultado = valor1 > valor2 ? valor1 : valor2;
printf("%f", resultado);
}
In this case, the use of the ternary operator could also be useful to improve the readability of the code.
@cat well remembered! Do you think it is advisable to post your question to him? https://answall.com/questions/92101/quando-devo-usar-o-operador-em-c
You can quote in your reply.

I believe it’s a syntax error in printf, try to write this way:
printf("%d", valor2)
Note also that you used print(valor1) and changed to print"f" (value2).
