Generally, printf() function is used to print the text along with the values. If you want to print % as a string or text, you will have to use ‘%%’. Neither single % will print anything nor it will show any error or warning.
Here is an example to print % in printf() in C language,
Example
#include<stdio.h>
int main() {
printf("%");
printf("%%");
getchar();
return 0;
}Output
%
There are some other ways to print % in the text message as in the following example,
Example
#include<stdio.h>
#include<string.h>
int main() {
printf("welcome%\n");
printf("%%\n");
printf("%c\n",'%');
printf("%s\n","%");
char a[5];
strcpy(a, "%%");
printf("This is a's value: %s\n", a);
return 0;
}Output
welcome% % 37 % % This is a's value: %%
