Managing Input and Output Operations 107 assigning it to many variable. (f) The specification particular character. may be used in scanf to terminate reading at the encounter of a decimal places. (g) The specification %[] is used for reading strings that contain (h) By default, the real numbers are printed with a precision of (i) To print the data left-justified, we must use (j) The specifier in the field specification. prints floating-point values in the scientific notation. 4.3 Distinguish between the following pairs: (a) getchar and scanf functions. (b) %s and %c specifications for reading. (c) %s and %[] specifications for reading. (d) %g and %f specification for printing. (e) %f and %e specifications for printing. 4.4 Write scanf statements to read the following data lists: (a) 78 B 45 (c) 15-10-2002 (b) 123 1.23 45A (d) 10 TRUE 20 4.5 State the outputs produced by the following printf statements. (a) printf ("%d %c%f", 10, 'x', 1.23); (b) printf ("%d %c %4.2f", 1234,, 'x', 1.23); (c) printf ("%d\t%4.2f", 1234, 456); (d) printf ("\"%08.2f\"", 123.4); (e) printf ("%d %d %d", 10, 20); For questions 4.6 to 4.10 assume that the following declarations have been made in the program: int year, count%;B float amount, price%3 char code, city [10]; double root%3 4.6 State errors, if any, in the following input statements. (a) scanf("%c%f%d", city, &price, &year); (b) scanf("%s%d", city, amount); (c) scanf("%f, %d, & amount, &year); (d) scanf( "%f", root); (e) scanf("%c %d %ld", *code, &count, Root); 4.7 What will be the values stored in the variables year and code when the data 1988, x is keyed in as a response to the following statements: (a) scanf("%d %c", &year, &code); (b) scanf("%c %d", &year, &code); (c) scanf("%d %c", &code, &year); (d) scanf("%s %c", &year, &code); 4.8 The variables count, price, and city have the following values: count
