<\/span><\/h2>\n\nTo capture the return value of fscanf, you need to assign it to a variable of type int. The return value indicates the number of items successfully read and assigned by fscanf. <\/p>\n
The following code snippet demonstrates how to capture the return value of fscanf:<\/p>\n
“`c
\n#include<\/p>\nint main(){
\n FILE* file = fopen(“data.txt”, “r”);
\n int integerValue;
\n float floatValue;
\n char characterValue;<\/p>\n
int returnValue = fscanf(file, “%d%f %c”, &integerValue, &floatValue, &characterValue);<\/p>\n
printf(“Return Value: %dn”, returnValue);<\/p>\n
fclose(file);
\n return 0;
\n}
\n“`<\/p>\n
In this example, fscanf reads an integer followed by a float and a character from the file “data.txt”. The variables integerValue, floatValue, and characterValue are passed by reference (using the address operator &) to store the values read. The return value of fscanf is stored in the variable returnValue, which will represent the number of items successfully read and assigned.<\/p>\n
